Water freezes at 0° Celsius, 32° Fahrenheit. This means that ice will be lighter than the same volume of water, and so ice will float in water. When water freezes, its molecules move farther apart, making ice less dense than water.

Water can occur in three states: solid (ice), liquid, or gas (vapor). How water can exist in three states on Earth? Depending on temperature and atmospheric pressure, water can change from one state to another, a process called physical phase change. Water is the only substance on Earth that naturally occurs in three physical states: solid, liquid, and gas (see Figure 4). Is water the only substance that can exist in three states? Water is the compound that exists in all three states of matter. Carbon dioxide is a good example of a substance which can be a liquid, but only when it is under pressure. Water is the only substance where all three states can be readily observed in everyday life: solid water as ice, liquid water in a water fountain, and gaseous water as steam. What can exist in all 3 states of matter?
