Question

p – V diagram of the ideal gas is as shown in figure. Work done by the gas in the process ABCD is

• A. $4p{V}_0$
• B. $2p_0{V}_0$
• C. $3p_0{V}_0$
• D. $p_0{V}_0$

Answer 1

The correct option is C $3p_0{V}_0$

$W_{AB}=-p_0{V}_0$
$W_{BC}=0$
$W_{CD}=4p_0{V}_0$
$W_{ABCD}=W_{AB}+W_{BC}+W_{CD}$
$=-p_0{V}_0+0+4p_0{V}_0=3p_0{V}_0$
