Q. An ideal gas $A$ and a real gas $B$ have their volumes increased from $V$ to $2\ V$ under isothermal conditions. The increase in internal energy
A) Of $A$ will be more than $B$
B) Of $A$ will be less than $B$
C) Will be same in both cases
D) Will be zero in both cases
Explanation
(d) Under isothermal conditions, $T =$constant
$\therefore$ Internal energy =constant $ie$, change in internal energy is zero
