Ice cubes are usually used to cool down or make iced drinks. According to the need, water can also be poured into the mold to make ice cubes with specific shapes. 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. With the increase of atmospheric pressure, the melting point of ice also increases.
Classification of ice
