Question

P-V diagram of an ideal gas is as 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. $P_0{V}_0$

Answer 1

Answer: (C)

$W_{AB}=-P_0{V}_0,$
$W_{BC}=0$
$W_{CD}=4P0V0$
$W_{ABCD}=W_{AB}+W_{BC}+W_{CD}$
$=-P_0{V}_0+0+4P_0{V}_0=3P_0{V}_0$
