An ideal monoatomic gas is allowed to expand from state point A to state point B according to the process AB. Then heat supplied to the gas is
P0V03
3P0V04
P0V04
12P0V0
At A temperature is T0
∴P02.2V0TB=P0V0T0⇒TB=T0
∴ΔU=Change to internal energy =n.CvT0−T0=0 W = Work done by the gas=12P0+P02.2V0−V0=3P0V04
∴Heat supplied =ΔU+W=3P0V04
