Interpretation:
The physical processes which are exothermic for water are to be chosen.
Concept introduction:
Freezing: The conversion of water into ice is freezing.
Boiling: The conversion of water into water vapors at boiling point is boiling.
Condensing: The conversion of water vapors into water is condensing.
Subliming: The conversion of ice directly into water vapors is subliming.
Evaporating: The conversion of surface water into water vapors is evaporating.

Answer to Problem 115A
Freezing and condensing
Explanation of Solution
That process is exothermic which occurs with release of heat.
Freezing and condensing are exothermic processes because these occur with release of heat.
The conversion of liquid into solid state and gaseous state into liquid state are exothermic.
