What is condensation
RUDIKE [14]

Condensation is the phase change from gas to liquid.  You can see condensation in the real world if you have a very cold drink.  A bottle of water filled with ice will attract water vapor from the air, and it will condensate around the bottle because the temperature is lower, which facilitates the phase change.  The outside of the bottle will contain a bunch of water droplets.

Hope this helps!!
