Condensation

Definition

Condensation is the phase transition from gas to liquid. It occurs when a vapor cools and loses enough thermal energy to change state.

5 Must Know Facts For Your Next Test

1. Condensation releases latent heat, which can cause temperature increases in the surrounding environment.
2. The process is crucial in the water cycle, forming clouds and precipitation.
3. Condensation occurs at the dew point, where air becomes saturated with moisture.
4. It can be observed on a small scale, such as fogging on a cold surface.
5. In closed systems, condensation can contribute to pressure changes.
