A.when ice melts, it should absorb heat. The higher the temperature, the faster it melts. When ice melts, it should absorb heat. The higher the temperature, the slower the melting. When ice melts, it releases heat. The higher the temperature, the faster it melts.

When the temperature is higher than zero degrees Celsius, the ice will begin to melt and become liquid water.

Ice is the solid form of water in nature. Under normal pressure, when the temperature is higher than zero degrees Celsius, the ice will begin to melt and become liquid water. When the solar ice begins to melt, it is an opportunity for a water molecule in the crystal to start to break away from the crystal, and the relevant mechanism is helpful to understand the mechanism of the structural change of protein containing water.

If the ice is irradiated with strong light such as electric light, the inside of the ice will melt and appear a shape similar to snow crystal, which is called "ice flower". In order to investigate the phenomenon of ice melting from the inside, researchers from Japan Institute of Molecular Science and Okayama University calculated by computer what happens to ice formed by about 1000 water molecules when heated.

The crystallization of ice is a hexagonal regular arrangement of water molecules. After heating, at first, a water molecule leaves the crystallization and starts to move freely, but this water molecule will not return to its original position, resulting in the distortion of the crystallization. Once the crystal is twisted, it will gradually expand, and eventually the whole crystal will fall apart and become liquid.

Extended data:

According to different uses, ice cubes are divided into the following types:

1, industrial ice:

Industrial ice, also known as ice cubes, ice bars, ice bricks, etc. It is frozen with pure tap water, and the temperature is about MINUS 20 degrees. Ice cubes are widely used in seafood, catering, hygiene, industry and food. Each ice cube is 50 cm long, 25 cm wide, 100 cm high and 200 kg net weight.

2. Edible ice:

Edible ice is 20 Jin per bag (edible). Sanitary edible ice particles are made by freezing sterilized edible water at MINUS 20 degrees, which can be used for eating, freezing, preparing drinks, mixing wine in hotels and so on. Drinks are cold, so wine and drinks are cold, refreshing, delicious, economical, applicable and delicious.

3, transparent ice:

Also known as crystal ice, clear ice and transparent ice, they can be used for scenery, artistic sculpture, decoration, celebration ice sculpture, wedding ice sculpture, reception ice sculpture, wine injection ice sculpture, business meeting ice sculpture, Chinese and English font ice sculpture, theme modeling ice sculpture, logo brand ice sculpture, ice-breaking ice sculpture, festival ice sculpture, annual ice sculpture, and ice sculpture design), ranging from wedding ice sculpture diamond ring to split ice sculpture.

4, crushed ice:

Crushing ice is to grind large ice cubes into powdery ice with an ice crusher, which is very convenient for seafood preservation.
