Evaporation:This process happens at the surface of a liquid and can occur at any temperature below the liquid's boiling point. It's a gradual process where molecules at the surface gain enough energy to escape into the surrounding air. Examples include water drying on clothes or puddles disappearing on a sunny day. Boiling:This is a more rapid process that occurs throughout the liquid, not just at the surface. It happens when a liquid reaches its boiling point, and bubbles of vapor form within the liquid, rising to the surface and escaping.
