Final answer:
Vaporization is the process of changing from a liquid to a gas.
Step-by-step explanation:
The process of changing from a liquid to a gas is called vaporization. Vaporization occurs when a liquid gains enough energy, typically through heating, to overcome the intermolecular forces holding its particles together. As a result, the molecules escape and become a gas. For example, when water is heated, it can vaporize and turn into steam, which is water in its gaseous state.
