Which process describes the change from a gas to a liquid?

The process that describes the change from a gas to a liquid is known as condensation. This occurs when gas molecules lose energy, often through a decrease in temperature, allowing them to come closer together and form liquid droplets. For instance, when warm, moist air comes into contact with a cool surface, the water vapor in the air loses energy and condenses into liquid water.

In general, vaporization refers to the transition from a liquid to a gas, which is the opposite of condensation. Freezing is the process where a liquid turns into a solid, and heating involves increasing the energy of a substance, which may lead to its state changing in the opposite direction. Therefore, condensation specifically addresses the transition from gas back to liquid.
