Concept explainers
Interpretation:
Among the given options, which process is an exothermic process has to be identified.
Concept Introduction:
A change of state is a cycle in that a substance is transformed from one physical state to another physical sate. The physical changes of a substance occurs by either heating or cooling. There are six possible changes of state and they are freezing, melting, evaporation, condensation, sublimation, and deposition. The below mentioned figure will represent each of the physical changes of a substance from starting stage to final stage via intermediate stage.
