The term used to describe the process of converting a liquid into a vapor is "evaporation." This process involves the transition of molecules in a liquid state into a gaseous state, which occurs when liquid particles gain enough energy to overcome intermolecular forces. Evaporation can be seen in daily life; for example, when puddles dry up after rain or when clothes dry after being washed. Factors that influence the rate of evaporation include temperature, humidity, and air movement. This process is fundamental in nature and plays a significant role in the water cycle, affecting weather and climate patterns.
