Question

P-V diagram of an ideal gas is an shown in figure. Work done by the gas in the process ABCD is

• A. $4P_0{V}_0$
• B. $2P_0{V}_0$
• C. $3P_0{V}_0$
• D. $3P_0{V}_0$

Answer 1

The correct option is C $3P_0{V}_0$

$W_{AB}=-P_0{V}_0{W}_{BC}=0and{W}_{CD}=4P_0{V}_0\therefore W_{ABCD}=-P_0{V}_0+0+4P_0{V}_0=3P_0{V}_0$
