Here's how it works:

* Heat Energy: When water is heated, the water molecules absorb energy and start to move faster.

* Breaking Bonds: As the molecules move faster, they break the weak bonds that hold them together in liquid form.

* Escape into the Air: The energized molecules have enough energy to escape the surface of the water and become water vapor in the air.

This process is happening all the time, even at room temperature, just at a slower rate. The hotter the water, the faster it evaporates.
