Interpretation: Whether the given process increases or decreases the water temperature should be determined.
Concept introduction: The system is the part of the universe that is taken under consideration.
Surroundings are the remaining portion of the universe excluding the system.
An endothermic process is one in which heat is absorbed by the system. Thus, the direction of the heat flow is from the surroundings to the system.
An exothermic process is one in which heat is released by the system. Thus, the direction of the heat flow is from the system to the surroundings.
