Answer:
exothermic
Explanation:
An exothermic reaction gives off heat energy. Condensation is the process by which water vapor turns into liquid water. This typically occurs when water vapor molecules come into contact with cooler molecules. This causes the water vapor molecules to lose some energy as heat which is a exothermic reaction.
When water becomes a solid, it releases heat, warming up its surroundings. This makes freezing an exothermic reaction.
