MCQ

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?

A
Process $A$ only
B
Process $C$ only
✓
Only Processes $C$ and $D$
D
Only Processes $B$, $C$ and $D$

✓

Answer

Correct option: C.

Only Processes $C$ and $D$

c
In $A$ temperature will increase

in $B$ temperature remains constant

in $C \& D$ temperature decrease.

Hence, option $C$ is the correct answer.
