Q. Two identical samples of a gas are allowed to expand (i) isothermally (ii) adiabatically. Work done is
A) More in the isothermal process
B) More in the adiabatic process
C) Neither of them
D) Equal in both processes
Explanation
(a) In thermodynamic process
Work done = Area covered by $PV$ diagram with $V$-axis
From graph it is clear that $(Area)_{iso} > (Area)_{adi}$
$\Rightarrow W_{iso} > W_{adi}$
