Q.
An ideal gas is taken from state $A$ to state $B$ following three different paths as shown in $p - V$ diagram, figure Which one of the following is true?
A) Work done is maximum along $AB$
B) Work done is minimum along $AB$
C) Work done along $ACB =$ work done along $ADB$
D) Work done along $ADB$ is minimum
Explanation
(d) $W = \int_{}^{}{pdV}$ =area under the $p - V$ curve
= minimum along $ADB$
