To change water from a liquid to a gas, the addition of energy is required. This process is known as vaporization (or evaporation, if it occurs at temperatures below the boiling point), and it involves providing heat energy to the water to break the hydrogen bonds between the water molecules, allowing them to escape into the air as gas (water vapor). There is no change in the chemical composition of water during this phase change; it remains H₂O in both liquid and gas forms.
