What change occurs when a liquid turns into a gas?

When a liquid turns into a gas, the process is known as evaporation. This transition occurs when molecules in a liquid gain enough energy, usually through heat, to overcome the attractive forces that hold them together, allowing them to escape into the air as gas. This process can take place at any temperature, not just at the boiling point, which is what distinguishes it from boiling.

In contrast, condensation refers to the process where a gas turns into a liquid, freezing is when a liquid changes to a solid, and melting is when a solid changes to a liquid. Therefore, the correct interpretation of the transition from a liquid to a gas is indeed evaporation.
