An increase in temperature caused the water molecules to gain energy and move more rapidly, which resulted in water molecules that are farther apart and an increase in water volume. When water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense.Click to see full answer. Similarly, it is asked, when water is heated does it turn into it?We learned that water has three states: ice is the solid state, water vapor is the gaseous state, and water is the liquid state. When water is heated it evaporates, which means it turns into water vapor and expands.One may also ask, does water expand when heated? Water is an unusual liquid and has unique properties, but it doesn’t behave the exact opposite of other liquids. Water does indeed expand when warms, and it contracts when it cools, but not at all temperatures. As water cools from 4 to 0 degrees Celsius, it expands because it’s crystallizing into ice. In this way, what happens when water cools down? If water loses enough heat energy (gets colder), it will freeze and turn into ice, the solid form of water. When water vapor in the atmosphere cools down, it will condense and change back into liquid water, forming clouds. This happens when water gains heat energy (gets hotter) or loses heat energy (gets colder).What happens to water at 100 C?When water reaches 100C it will be still liquid. Then you have to add more heat at constant 100C before water will start boiling. It is called heat of change of state. The boiling temperature of water (and all liquids for that matter) depends on pressure and whatever substances are present in it.
