Why do ice cubes stick together?
Because the temperature is higher than 0℃, a small part of the ice cubes become invisible water droplets, and if two ice cubes collide, if the collision area is large, the water droplets in the middle will become ice and stick together.

Pure water in nature will freeze at 0℃ under normal atmospheric pressure. If water contains impurities, the freezing point of water will drop. The melting point of ice is the freezing point of water. With the increase of atmospheric pressure, the melting point of ice also increases.

Naturally formed ice is called natural ice, and ice usually made by artificial refrigeration is called artificial ice, machine-made ice or industrial ice, among which there are many kinds of artificial ice, and the commonly used ice is industrial ice, edible ice and dry ice.

2. Edible ice: 20 kilograms of edible ice 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.
