What answer does ice belong to?

Ice is a refrigerant and a solid form of water.

Ice is a solid condensed by water at or below 0℃, usually in different forms such as crystal or powder. Ice is a very common existence in nature, which occupies about 70% of the fresh water reserves on our planet.

The main reason for the formation of ice is that water molecules will arrange in a compact crystal structure at low temperature, which will reduce the kinetic energy of water molecules and then reach below freezing point. When water molecules gradually condense into ice at low temperature, their density and hardness will gradually increase.

When water condenses into ice, or ice is melting into water, its overall mass will not increase or decrease, but its volume and density will change in a visible way. When the temperature rises from minus six degrees Celsius to zero degrees Celsius, the ice will expand and become bigger. When the temperature rises from zero degrees Celsius to four degrees Celsius, the effect is the opposite, and its volume will become smaller.

Ice may also do some harm. For example, large-scale freezing weather may cause the water level of rivers, lakes and other water bodies to rise, which may lead to natural disasters such as floods.

Use of ice:

1, cooling and keeping fresh: ice is a good coolant and preservative. In the process of food processing and storage, ice can effectively reduce the temperature of food and maintain its freshness and taste. For example, when making cold drinks, ice can be used to cool drinks and keep their taste fresh. In long-distance transportation and storage, ice can be used to keep food fresh and prevent food from going bad.

2. Create ice and snow sports: Ice is the foundation of ice and snow sports. In winter, people can ski, skate and other ice and snow sports on the frozen lake or snowfield. These sports need a lot of ice to make ice, ice walls and other facilities, providing a good competition environment for athletes.

3. Making artworks: Ice can be used to make various artworks. In the cold winter, people can make ice sculptures, ice lanterns and other works of art outdoors. These artworks not only have high ornamental value, but also add festive atmosphere to festivals and celebrations.

4. Prevent scale: When boiling water or cooking soup, adding some ice cubes can reduce the generation of scale. This is because under the action of ice, minerals such as calcium and magnesium in water are not easy to precipitate, thus reducing the generation of scale.
