Condensation Next Topic: Contrails

Condensation is the process which creates clouds, and therefore it is a crucial process in the water cycle. Condensation is the change of matter from a state of gas into a state of liquid, and it happens because water molecules release heat into the atmosphere and become organized into a more closely packed structure, what we might see as water droplets.

Water is always present in the air around us as a vapor, but it's too small for us to see. When water undergoes the process of condensation it becomes organized into visible water droplets. You've probably seen condensation happen before on the surface of a cold drink!
