What is the difference between boiling and evaporation?

• Boiling happens at any temperature, evaporation happens at boiling point

• Boiling depends on surface area, evaporation does not depend on surface area

• Boiling has a cooling effect, evaporation has no cooling effect

• Boiling happens throughout the liquid, evaporation happens on the surface
