Ice generally refers to solid water made by freezing liquid water. Usually used to cool down or make iced drinks. As required, water can also be poured into the mold to make ice cubes with specific shapes, such as popsicles.
Pure water in nature will freeze at 0℃ under normal atmospheric pressure. If water contains impurities, the freezing point of water will decrease with the increase of pressure. The melting point of ice is the freezing point of water, and the melting point of ice decreases with the increase of atmospheric pressure.
