What is formed during the process of condensation?

During the process of condensation, water vapor in the air cools down and changes back into liquid water. This occurs when the air reaches its dew point, and the temperature drops to a level where it can no longer hold the moisture in a gaseous state. As the vapor molecules lose energy, they come closer together and aggregate to form liquid droplets. This is commonly observed when you see dew forming in the morning or when water droplets appear on the outside of a cold glass.

The other options describe different states or forms of water: solid water refers to ice, water vapor is the gaseous state of water, and ice crystals specifically refer to the solid structure that forms under freezing conditions. Condensation specifically transitions water from vapor to liquid, making liquid water the correct response in this context.
