Question

the act or process of changing from a gas or vapor to a liquid.

Answer 1

The act or process of changing from a gas or vapor to a liquid is called **condensation**. This process can occur when gas is cooled to its dew point, leading to the formation of liquid droplets. Condensation is commonly observed in daily life, such as when water vapor in the air forms droplets on a cold surface, like a glass of ice water.
