In what processes of gas compression or expansion does the temperature remain constant?

Question

Quizplus · Accepted Answer

In isothermal processes, the temperature remains constant. This can occur during gas compression or expansion as long as the process happens slowly enough to allow for heat exchange with the environment to keep the temperature constant. Adiabatic processes (B) do not allow for heat exchange and therefore temperature changes can occur. Hypothermal (C) and neutral kinetic (D) are not recognized terms in this context.
