Answer:
Condensation is when a gas becomes a liquid. It happens when a gas, like water vapor, cools down. ... Evaporation and condensation happen when these molecules gain or lose energy. This energy exists in the form of heat.

Answer:
Explanation:
When a gas loses enough kinetic energy the constituent molecules will begin to associate via attractive forces. This process is called condensation. During this transition the temperature will remain constant until the gas has transitioned completely to the liquid state. This is an exothermic process where heat will be liberated from the system.
