Question

The PV diagram shows four different possible reversible processes performed on a monoatomic ideal gas. Process A is isobaric (constant pressure). Process B is isothermal (constant temperature). Process C is adiabatic. Process D is isochoric (constant volume). For which process(es) does the temperature of the gas decrease?

TestHub · Accepted Answer

A (isobaric expansion): T ∝ V rises. B (isothermal): T constant. C (adiabatic expansion): T falls. D (isochoric pressure drop): T ∝ P falls. So C and D.
