The Changing Phases of Matter: Liquid to Gas Phase Change

The video explains the phase change of vaporization, where a liquid turns into a gas. It covers evaporation, which occurs at the surface of a liquid, and boiling, where gas bubbles form within the liquid. The opposite process, condensation, is also discussed, where gas turns back into a liquid, as seen on cold surfaces or in cloud formation.

What is the process called when a liquid changes into a gas?

Describe the process of evaporation and where it occurs.

What happens to water vapor when it cools down?

Explain how clouds are formed through condensation.
