A special situation has arisen. And you urgently need ice for some purpose. Water freezes at 0 degrees. At first glance, the question itself will seem stupid. After all, what other solution to this problem could there be if not: take a container of water and put it in the freezer. There is one thing. Water will take a very long time to freeze due to its specific heat capacity. And you will have to wait a very long time for the ice you need.
We all know from our school curriculum that water freezes at a temperature of 0 degrees Celsius. What could be easier than getting ice? It is enough to put water in the freezer and after a while take out the resulting ice. But the water takes a long time to cool down and the process may drag on. Let's consider the question of how to quickly freeze water?
The speed at which water freezes depends on two factors. The first is the surface area of the container into which water is poured, and the second is the thickness of the water layer. The smaller the area and the greater the thickness of the layer, the longer it takes for the water to freeze and ice to form. And, naturally, vice versa. This means, as you understand, you need to pour water into a shallow and wide bowl. For these purposes, so-called plastic containers for obtaining ice at home are suitable. Pour water into such a container and place it in the freezer. Ice forms much faster than if you put water in a plastic jar or glass.
The process of freezing water can be somewhat speeded up if you use regular table salt. You need to pour water into an ice container and put it in the freezer. When the water begins to freeze, throw 1-2 grains of salt into each cell or compartment of the container, and almost fresh water will freeze faster, despite the fact that salt water takes longer to freeze. It's strange, but it's true. Salt crystals will serve as the so-called beginning of water crystallization, while the mass of salt will be insignificant.
You can freeze water and make ice using liquid nitrogen. If you have a Dewar flask, then the process will also not be difficult and fast. A long metal container, such as a test tube, must be filled with water and lowered into a vessel with liquid nitrogen. Be sure to use tongs or a clamp. Care must be taken to ensure that nitrogen does not completely fill the container. After a few minutes, remove the container from the vessel, and as soon as the walls begin to heat up, the ice can be easily removed.
Chemicals can be used to make ice quickly. Some of them absorb large amounts of heat when dissolved. Ammonium nitrate, or ammonium nitrate, is one such chemical used in agriculture. If you need ice for purposes other than food, there is no simpler way to do it. Dissolve the saltpeter in a container of water, making sure to stir, and place it in the freezer. After a few minutes, the finished ice can be removed from the freezer.
Physical properties of water when frozen in the freezer
The rate at which water freezes is determined by the heat transfer surface area and the thickness of the water layer. The wider the layer, the longer the water will freeze, and vice versa.
Pour water into a container that has a large area, pour it so that the thickness of the water layer remains small.
How to clean the drain pipe in a Samsung refrigerator?
The easiest way to clean the drainage tube is with a syringe or syringe. To do this, add a little dishwashing liquid to warm water. Fill a syringe or syringe with the resulting composition and then forcefully inject it into the drainage hole. If necessary, this procedure is repeated several times.

What should the water temperature be before freezing?
There is still no clear answer to this question. Although the Royal Society of Chemistry has made up its mind, it has not completely stopped the debate. New hypotheses are still being put forward and refutations are being made.
Although there is a small clue: the popular science magazine New Scientist conducted research and came to the conclusion that the best conditions for repeating the Mpemba effect are two containers of water with temperatures of 35 and 5 ° C.
Thus, if there is very little time left before the party, fill the ice trays with water, the temperature of which is comparable to room temperature in the hot summer. It is better not to use well or cool tap water.
Add syrups before freezing
As you know, any ice cream tastes better if you prepare it with various additives. Among them, syrups with all sorts of flavors are very popular. Chocolate, caramel, pistachio, coconut, strawberry - this is just an incomplete list of popular syrups from which you can make delicious ice cream. It is important to remember that syrups are added to milk or cream mixtures before freezing.
How to make crushed ice

Where to get solid CO2
The easiest option is to order ready-made kits for experiments with dry ice. In addition, there are many companies that manufacture and sell the substance. The same companies offer containers for its delivery. A container is necessary because without it the crystals will melt or, more correctly, sublimate. The warmer the transport and storage conditions, the more CO2 will evaporate.
You should not buy solid carbon dioxide in reserve. Buy it as close as possible to the time you need it. If the company offers a large batch (this is usually the case), try dividing it among several people: maybe your friends with children also want to experiment with ice. If there is no special company in the city, try to buy some of the substance from animators who make soap bubbles or a science show.
One kilogram costs about 90 rubles. The cost of a container for transportation and storage is from 500 rubles. One experiment will require from 30 to 500 grams of the substance.
Solid CO2 comes in lumps, cubes and granules. Carefully study the description of the experiments and decide which form is more convenient for you.
Correct form
You can quickly freeze water if you choose the appropriate forms for this. The smaller the size of the finished cube, the faster it will form. In addition, thin and elongated rectangles and unusual complex shapes freeze faster. The fact is that the water will have a large contact area with the directly cooled surface. As a result, the ice will not only require less time to prepare, but will also be more transparent and less cloudy. It is not difficult to find similar forms on sale. With their help you can get ice hearts and stars that children will definitely like.
Secrets of properly freezing strawberries for the winter
Strawberry season is in full swing, which means it’s time to think about winter preparations. Freezing can easily be called the best...
Freezing will take place quickly if you use special disposable or reusable bags. You can fill them with water through a special valve. The form itself will fit even in a crowded freezer, since it is not rigid, but flexible. The walls of the bag are much thinner, they conduct heat better. They are completely adjacent to the surface of the shelf, which also speeds up the process. The cubes themselves will be small.
On a note!
This size is good for soft drinks or cocktails, but not for noble and complex drinks. In a small glass, a little ice will instantly melt, diluting the original product.
Experiments with dry ice for children from three years old
- Inflating a balloon (3+)
Place some ice inside a regular balloon and tie a tail. Then the magic will happen on its own. The carbon dioxide will sublimate and miraculously inflate the balloon. The main thing is not to overdo it with the amount of substance, otherwise the ball will not withstand it and will burst. Although the explosion may well be part of the trick.
- Giant bubble (4+)
Place a block of dry ice weighing 500–700 grams at the bottom of the dish and fill it with hot water. The reaction will happen instantly - white steam will pour out of the dish.
Now we need to act quickly. Soak a piece of cloth or rope in the soapy solution and pass from one edge of the dish to the other over the steam so that a soap film forms. After a few seconds, the substance will turn into gas, stretch the soap film and a huge bubble will grow above the plate, similar to a magic fortune ball.
- Putting out the candle (5+)
This is an experiment for children that is more educational than spectacular. Place a candle inside a vase or jar and light it. The candle will burn evenly and easily. Throw a few pieces of CO2 into the jar and after a short time the fire will go out because the carbon dioxide does not burn.
- Magic smoke (4+)
Pieces or granules of solid carbon dioxide are simply thrown into a bowl of hot water. The container turns into a mystical witch's cauldron.
The secret of the trick is simple: when it gets into hot water, carbon dioxide goes from a solid state to a gaseous state much faster. Interestingly, it does not have a liquid state. With older children, you can delve deeper into physics and consider the topic “The Three States of Matter.”
- Floating bubbles (3+)
Soap bubbles appear alive if you blow them into a container with a few pieces of CO2. The released gas prevents the bubbles from falling, and they beautifully float in the air above the ice crystals.
- Smoke balls (5+)
A hole is cut or burned in the bottom of the plastic bottle of such a size that a rubber tube or plastic straw fits tightly into it. Insert the tube into the hole. Place some dry ice in the bottle and close the cap tightly. Dip the end of the tube into the soapy solution and watch the steam-filled bubbles inflate.
The gas stretches the soap film at the end of the straw and blows out the bubbles. Try “planting” such a bubble on a child’s hair or a woolen mitten.
You may come up with other interesting tricks with dry ice: you can use it to make soda, freeze plants with it, and use it in smoky discos. The ideas are endless!

Why does ice form under the drawers in the freezer?
The manual defrosting chamber is a cabinet with a double body, foamed with polyurethane. The inner chamber has structures made like stands for boxes or trays made of thin aluminum sheet. Evaporator tubes are connected to each shelf below.
Products are placed in drawers or behind doors. During freezing, water is released and settles on the tubes, which is why ice freezes under the drawers in the freezer. Therefore, it is dangerous to allow a large layer - it is difficult to remove products, and you can accidentally damage the tube.
Ice formation in the freezer compartment under the shelves is a natural physical process. But ice is an insulator and impairs heat transfer. The larger the snow build-up in the chamber, the longer the compressor cycle, and the more energy is spent on freezing food.
How long does it take to freeze water in the freezer?
If you just put an ice tray with water, the water will freeze in about 30 minutes. If you put a 1.5 liter bottle of water, the freezing process will last approximately 1.5-3 hours.

Why does ice freeze in the freezer below?
It happens that food in the freezer thaws due to lack of or low voltage in the network. If the refrigerator turns on on its own after being idle, the resulting puddle may go unnoticed and freeze, creating ice under the freezer.
With the maximum freezing mode, when the door is opened, the frost melts and flows down in drops, where it freezes. You need to maintain an average temperature - less frost, economical energy consumption. By following the manufacturer's recommendations, you can ensure that ice does not accumulate at the bottom of the freezer.
Chemical effects
Some substances can accelerate freezing processes by changing the rate of heat transfer. For this purpose you can use:
- table salt;
- lemon juice;
- ammonium nitrate.
With a high salt concentration, the solution will harden worse, and the same thing happens if there are a large number of impurities. Therefore, it is better to use filtered liquid, this will turn into ice much faster. But if used correctly, coarse table salt will become a full-fledged catalyst for the reaction. When the total mass of water poured into the mold cools down greatly and begins to change its structure, you can simply add one grain to each cell. They will become the center of crystallization, the water will harden faster. However, this will not affect the taste in any way.
You can use citric acid or citrus juice in a similar way. At the same time, it is easy to change the taste of the ice by adding more or less. But it’s better to experiment with freshly squeezed juice rather than packaged juice. It does not contain sugar, which slows down the freezing process.

Why does ice form on the freezer door?
It happens that the alarm indicates a violation of the regime in the freezer - the door is not closed tightly or the seal has come off. Ice freezing is accelerating. Now it is loose, reminiscent of snow, wraps the lids of containers, and settles on the door. The cold passes through such a fur coat with difficulty, the compressor runs non-stop.
The reason for the accelerated freezing of ice in the freezer is the continuous supply of fresh air. The warm agent contains a lot of equilibrium moisture, which precipitates on cold surfaces. But frost frozen on the door widens the existing gap, increasing icing. A warm refrigerant circuit runs around the doorway in the foamed part. The ice melts, leaks under the bottom drawer, and ice forms on the bottom of the freezer.
If the freezer is electronically controlled, the regulator will stop distributing cold into the open circuit and the food will begin to thaw.
How to store dry ice and how to work with it
At home, ice is stored in a special container or cooler bag. If it's cold outside, the container can be placed outside the window.
- Do not store in an airtight container, freezer or poorly ventilated area. In the first case, an explosion may occur, and in the second, the room will be filled with carbon dioxide and it will be difficult to breathe in it. When conducting experiments at home, be sure to ventilate the “laboratory” well.
- When working with solid carbon dioxide, we recommend wearing gloves and long sleeves. Prolonged contact with ice flakes can result in burns. Because of this, you should not trust his children - all classes are conducted strictly under the guidance of an adult.
- The substance should not be held with bare hands for a long time and tasted. Moreover, the steam generated from it is completely safe.

Additional Operating Notes
- The cooling mode must be selected correctly. A high ambient temperature does not mean that it is necessary to set the freezer to the maximum possible power.
- Placing containers with hot food in the refrigerator may cause the temperature sensor to malfunction. If it is also open, the actively evaporating moisture will lead to the formation of ice. Often, this becomes the simplest cause of ice formation.
- Do not overload the refrigerator with food. This may cause the compressor to overload. Extreme operating mode will lead to its failure.

Why does ice form?
One of the likely causes of ice may be a power outage. The mains voltage has gone out, so the refrigerator does not freeze. As a result of downtime, a puddle may appear; the fact that it appears is not always clearly visible and may go unnoticed. After operation is restored, it freezes and ice forms.
Setting the maximum freezing mode can lead to untidy consequences. When you open the door, frost forms, which begins to melt and drip down, resulting in the formation of ice.
To avoid this, it is recommended to keep the freezing temperature at medium. This will not only prevent the occurrence of frost, but will also save some energy. According to the recommendations of most manufacturers. This mode of operation is the most optimal.
Naturally, opening and closing the door is not the only circumstance leading to the occurrence of icing. The reasons for this phenomenon may include the following:
- Broken door seal. Wear of the rubber seal may result in the door not fitting tightly to the refrigerator body.
- Another reason why ice forms in a refrigerator with the NoFrost system may be clogging of the channels leading water from the heat exchanger with foreign inclusions. Also, one of the pipes could simply have jumped out, as a result of which moisture does not enter it and the movement of water to the container for collecting moisture does not occur.
The container itself is usually located in the same compartment with the motor. Water evaporates from it naturally. The occurrence of icing may be due to the fact that the resulting water does not get to the required place, but is poured into the freezer. There it freezes safely.
- Malfunction of the heating element of the heat exchanger, that is, its combustion. In this case, no one except a service specialist can help.
Important! If the appearance of ice is observed regularly, and the refrigerator is still under warranty, then you should not look for reasons. Moreover, carry out independent repairs. Contact the seller to fix the problem or replace the technical device.
Theory
Homemade ice turns cloudy due to gases (including oxygen), mineral salts and other impurities contained in the water. The gases form tiny bubbles that, when frozen, form crystals that are too large. Heavy metal salts act in a similar way. Only purified, degassed water of low hardness provides complete transparency.
The difference between conventional freezing and the proposed technology
Ingredient:
water (purified or distilled) – 1 liter.
Depending on the number and variety of drinks, an average of 600-800 grams of ice is required per party participant.
Usage[edit | edit code]
Speed traveledit | edit code
Due to the slippery properties of ice, it can be used to change the mechanics of entity movement, including the movement of objects.
If you create a flow of water on the surface of ice, then objects will move with the flow much faster.
If you build a tunnel 2 blocks high and 1 block wide with ice on the base, and then run through it, often pressing the jump key, you can easily reach a speed of 15-20 blocks/s, which is twice as fast as the maximum speed trolleys. It should be noted that with this method of movement, the hunger scale is quickly spent.
Players on a boat can move quickly across the ice, reaching speeds of up to ~40 blocks/s, but turning is difficult due to sliding. This property can be used to build a high-speed “ice” metro to quickly move the player between remote points of the game world, in addition, ice does not melt in the Lower World in the absence of nearby bright lighting sources, so you can lay an ice route with a network of portals there, speeding up movement even more 8 times in projection onto the upper world.
Transportation of wateredit | edit code
Since ice can be stacked into 64-piece stacks, unlike water buckets, it can be used to transport water sources in a space-saving manner.
Ice at the bottom of the No Frost freezer
If the freezer uses a convective method of transferring cold from the evaporator to the food, there should be no frost inside. The evaporator is located behind the panel in the cooling compartment, there is also a fan, a defrosting heating element and a hole for removing condensate from the circuit.
What happens is that the hole becomes clogged, the drainage hose freezes, sticks together, and water accumulates in the chamber with the evaporator, freezes in a lump, seeps into the working chamber, forming ice in the freezer. Soon, No Frost will become inoperable due to accumulated ice and a frozen fan. Sometimes the drops from behind the panel take a long time to roll down, and blocks of ice freeze directly in the trays in the freezer.
If the panels are cold, a thin layer of ice will freeze on the walls of the No Frost freezer. Gradually it will melt and drip onto the tray. What to do if ice freezes in the box? Turn off the refrigerator or freezer compressor, defrost the system and look for a malfunction.
Secrets to getting ice quickly
And the last secret for lovers of various chemical processes. There is a substance called ammonium nitrate or ammonium nitrate. The properties of this chemical dissolve, absorbing almost all the heat. This substance, by the way, is often used as a nitrogen fertilizer in agriculture.
If you need ice for non-food purposes, add ammonium nitrate to a container of water and mix everything. Then place the container in the freezer. In a couple of minutes the ice will be ready.
At what temperature does water freeze in the freezer?
It would seem that the answer is obvious. Zero. Someone will remember that sea water freezes at minus three to four degrees below zero Celsius. Because seawater contains salts and minerals that shift the freezing point. Also, you probably already know that NASA space agency scientists have published a report about the water found on Mars, which does not freeze at a planetary temperature as low as minus 25 degrees below zero Celsius. Of course, this substance is called water very arbitrarily, since the chemical composition in this liquid can kill anyone. That is, it is obvious that the freezing temperature depends on the composition of the water: the more foreign molecules contained in H2O, the less susceptible the water is to the crystallization process at low temperatures.
However, the following scientist turns everything on its head - it turns out that if you try to freeze perfectly clean water, without impurities, and most importantly - without dust particles (even microscopic), then such water can only freeze at minus 43 degrees Celsius! This phenomenon is explained by the fact that ice crystals have nothing to “catch onto” - there is no center of crystallization.
And that is not all! Water can be cooled to low temperatures (a couple of tens of degrees below zero Celsius) bypassing the crystallization stage in its classical form. This effect is known as “hypothermia.” This effect is achieved in cases where the purified water is at rest and very carefully placed in the freezer for a couple of hours. But as soon as you take out such water and jog a little (or even click your finger on the bottle), the water will instantly turn into ice (even though it sounds like science fiction).
Well, and finally, another interesting fact about water freezing: hot water freezes faster than cold water. There is no exact scientific basis for this effect today (although it was proven in 1963), most likely this is due to the fact that water molecules that evaporate from a hot liquid undergo instant freezing (as a less dense substance than water itself) and form primary centers of crystallization and further cooling of all remaining liquid.
