Q. A pressure $P$-absolute temperature $T$ diagram was obtained when a given mass of gas was heated. During the heating process from the state 1 to state 2 the volume
A) Remained constant
B) Decreased
C) Increased
D) Changed erratically
Explanation
(c) [image:13_image23.emf]
$PV = \mu RT$
$\Rightarrow V \propto \frac{T}{P}\ (\because\mu$ and $R$ are fixed$)$
Since, $T$ increases rapidly and $P$ increases slowly thus volume of the gas increases
