What happens to the molecules within a gas when the gas condenses? they gain energy. they lose energy. they drift apart. they move faster.

In evaporation, a liquid (like water) changes state to become a gas (water vapor). In condensation, a gas (like water vapor) changes state to become a liquid (water). Explain that as water molecules in the air cool and slow down, their attractions overcome their speed and they join together, forming liquid water.
