Why does dry ice smoke when put in water?
Dry ice refers to solid carbon dioxide, which will evaporate rapidly at room temperature and produce a large amount of carbon dioxide gas. When dry ice comes into contact with water, it will evaporate rapidly due to its chemical properties, producing a large amount of carbon dioxide gas. When these gases come into contact with air, they form white smoke. This is because after the sublimation of dry ice, carbon dioxide gas combines with water vapor in the air to form carbonic acid droplets, and these droplets gather together to form the white smoke we see. In addition, when dry ice is mixed with water, it will absorb the heat of the surrounding environment and make the water very cold, which is one of the reasons why dry ice smokes after adding water.
