Question

Which is true about evaporation and condensation?

A) Evaporation releases heat
B) Condensation absorbs heat
C) Evaporation is a cooling process
D) Condensation is an endothermic process

Answer 1

Evaporation is a cooling process while condensation is an exothermic process that releases heat into the surroundings.

Step-by-step explanation:

Evaporation is a cooling process and condensation is an exothermic process that releases heat into the surroundings.

When a liquid evaporates, it absorbs heat from its surroundings, resulting in cooling. This is because the molecules gain enough energy to overcome intermolecular forces and escape as a gas. As a result, the temperature of the surrounding environment decreases.

On the other hand, condensation is the phase change from a gas to a liquid. During condensation, heat is released from the gas molecules, which increases the temperature of the surroundings.
