Here's a breakdown:
* Evaporation: This is a gradual process where liquid molecules at the surface gain enough energy to escape into the air as gas. This happens at temperatures below the liquid's boiling point. Think of a puddle slowly drying up in the sun.
* Boiling: This is a more rapid process where liquid molecules gain enough energy to escape from anywhere within the liquid, forming bubbles of gas that rise to the surface. This happens when the liquid reaches its boiling point. Think of water boiling in a pot.
Both evaporation and boiling involve the same basic principle: heat energy causes the molecules in the liquid to move faster and break free from the liquid state. The higher the temperature, the faster the molecules move, and the more likely they are to evaporate or boil.
