Phase change when heat is removed from a gas?

Explanation:
When heat is removed from a gas, its molecules slow down and come closer together. As the gas cools to its condensation point, the attractive forces pull the particles into a more ordered, denser state—a liquid. This gas-to-liquid change is condensation. Other processes involve different directions of energy transfer or states: evaporation requires adding heat to a liquid to become gas, sublimation is solid turning directly into gas, and freezing is liquid turning into solid.
