The process of turning liquid into gas is known as vaporization. It occurs when molecules in a liquid gain enough energy to overcome intermolecular forces, allowing them to escape into the air as gas. Vaporization can happen in two main ways: evaporation, which occurs at the surface of a liquid at any temperature, and boiling, which takes place when a liquid reaches its boiling point and bubbles form throughout the liquid. This process is vital in various natural phenomena, such as the water cycle, where water evaporates from oceans and lakes, contributing to cloud formation and precipitation.
