Evaporation is the process by which a liquid turns into a gas. It is also one of the three main steps in the global water cycle.
Evaporation occurs when energy (heat) forces the bonds that hold water molecules together to break. When you're boiling water on the stove, you're adding heat to liquid water. This added heat breaks the bonds, causing the water to shift from its liquid state to its gaseous state (water vapor), which we know as steam.
Evaporation occurs from the surface of a liquid because the molecules at the surface of the liquid have higher kinetic energy than the molecules in the bulk of the liquid. This causes them to escape the surface and become vapor, leaving the lower-energy molecules behind. The process is a type of vaporization that happens at temperatures below the boiling point of the liquid.
