Addition or removal of heat energy.
Water changes state depending on its temperature and pressure. When water is heated, it can change from a solid (ice) to a liquid (water) to a gas (steam). When water is cooled, it can go from a gas to a liquid to a solid. These changes in state are due to the energy levels of the water molecules.
temperature
When water boils it changes from a liquid state to a gaseous state.
The only changes of state in pure boiling water is from liquid to gas.
The density changes.
Matter changes state because of temperature and pressure. These quantities bring change.
The process that changes water into a gaseous state is called evaporation, where water is heated and transforms into vapor or steam.
different climate changes in the water
In evaporation, a liquid such as water changes to a gaseous state. In sublimation, a solid such as ice changes driectly to a gas or vapor without going through a liquid state.
When water changes into a solid it becomes a solid!
Evaporation causes water to become a vapour.
