Water vapor forms when liquid water evaporates, transitioning from a liquid state to a gaseous state. This process occurs when heat energy increases the kinetic energy of water molecules, allowing them to break free from the surface of the liquid. Additionally, water vapor can also be produced through processes like sublimation, where ice changes directly into vapor without becoming liquid first. Factors such as temperature, humidity, and air pressure can influence the rate of evaporation and the amount of water vapor present in the air.
