Which statement about the evaporation of a liquid is not correct?
Evaporation happens only at one particular temperature.
Evaporation happens only at the surface of the liquid.
Evaporation happens when the more energetic molecules escape from the liquid.
The energy required for evaporation can cause the liquid to cool.
