The word water usually refers to water in its liquid state. Water in its solid state is frozen and is more commonly known as ice. Water can also be a gas in the form of steam or water vapor. Water freezes at temperatures below 32 degrees Fahrenheit. Ice begins to melt when the temperature around it begins to rise above 32 degrees Fahrenheit. Unlike most substances, water expands when it freezes. This is why an ice cube will take up more space than it did as the liquid water it was made from.
In winter, many regions experience very cold temperatures. Any water on surfaces such as roads and sidewalks will freeze and become hazardous to drive or walk on. In some of these regions, salt is frequently used to help melt the ice. When salt is added to a block of ice, the area of ice immediately surrounding the grain of salt begins to melt. The melting process spreads out from that point. This is because salt lowers the freezing point of water.
