Q. The change in volume $V$ with respect to an increase in pressure $P$ has been shown in the figure for a non-ideal gas at four different temperatures $T_{1},T_{2},T_{3}$ and $T_{4}.$ The critical temperature of the gas is
A) $T_{1}$
B) $T_{2}$
C) $T_{3}$
D) $T_{4}$
Explanation
(b) At critical temperature the horizontal portion in $P - V$ curve almost vanishes as at temperature $T_{2}.$ Hence the correct answer will be (b)
