* State change: Condensation is the process of a gas (like water vapor) changing into a liquid (like water droplets).

* Energy and states: Molecules in a gas have more kinetic energy (energy of motion) than molecules in a liquid. To change from a gas to a liquid, the molecules need to slow down and get closer together.

* Energy release: This slowing down and closer packing releases energy. This energy is often felt as heat, which is why condensation can make surfaces feel warm.

Think of it this way: When water evaporates, it absorbs energy from its surroundings to break the bonds holding the molecules together as a liquid. Condensation is the reverse, and it releases that energy back into the environment.
