What happens during evaporation?
What happens during evaporation?
- Molecules at the surface gain enough energy to enter the gaseous state (correct)
- Molecules lose energy
- Molecules at the bottom of the liquid gain energy
- Liquid turns into a solid
Why does evaporation occur at any temperature?
Why does evaporation occur at any temperature?
- Because molecules have to reach a specific temperature to evaporate
- Because air particles collide with the liquid providing energy for molecules to escape (correct)
- Because only some molecules can evaporate
- Because liquids are always at a high temperature
