Question

The PV diagram shows four different possible reversible processes performed on a monatomic 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

T = n R P V ​ . A: P constant, V increases ⇒ T increases. B: T constant. C: at any V , P is less than on isotherm B ⇒ T < T B ​ : temperature decreases. D: V constant, P decreases ⇒ P V decreases ⇒ T decreases.
