Water vpor changes to liquid water?

Answer 1

Water vapor is turned into liquid water by condensation. This is when it is cooled. Sometimes, when you use a kettle by a window, the steam (water vapor) hits the windows and drips water. This because the water has condensed.

Answer 2

When water vapor cools down sufficiently, it undergoes condensation and changes into liquid water. This process involves the molecules of water vapor losing energy and coming together to form liquid droplets. It occurs when the temperature drops below the dew point of the air.
