Water does not commonly form a gas, but rather a vapor which is slightly different (but really just the name of a gas that is normally a liquid). - There is latent heat in water so you can remove energy without changing the temperature of the water (only exactly at a phase change though).
Water is the only substance that exists on Earth in each of its. three states. Water easily changes from one state to another. Water. sometimes changes its location by changing state in a continuous. pattern called the water cycle. Th e water cycle is self-renewing and. constant. Th e Sun provides the energy to power the water cycle. Changes of State. When water changes state in the water cycle, the total number of. water particles remains the same. Th e changes of state include melting, sublimation, evaporation, freezing, condensation, and deposition.
