Question

Evaporation produces cooling. Comment on the following statement.

Answer 1

Energy conversion for evaporation:

1. Evaporation is the process of converting liquid into vapor by applying heat.
2. Evaporation causes energetic molecules to exit the liquid phase, lowering the average energy of the remaining liquid molecules.
3. The liquid molecules that remain can then absorb energy from their surroundings.

Evaporation system:

1. During evaporation, liquid particles gain energy from their surroundings in order to overcome the force of attraction between them.
2. As a result, heat energy is lost in the surroundings.
3. It is clear from the preceding explanation that evaporation causes cooling.
