Question

A graph between pressure p (along Y-axis) and absolute temperature T(along X-axis) for equal moles of two gases has been drawn. Given that volume of second gas is more than volume of first gas. Which of the following statement(s) is/are correct? [JIPMER 2017]

Moderate

A

Volume of gas 1 is less than that of gas 2.
B

Volume of gas 1 is more than that of gas 2.
C

Both have same volume.
D

None of the above

Solution

According to ideal gas equation, pV = nRT
$\Rightarrow$ $\frac{p}{T} = \frac{n R}{V}$
where, $\frac{p}{T}$ represents slope of the graph.
As, the number of moles are same for the two gases.
$\Rightarrow$ $\frac{p}{T} \propto \frac{1}{V}$
$∵$ $V_{2} > V_{1}$ (Given)
$∵$ (Slope)₂ < (Slope)₁ or (Slope)₁ > (Slope)₂
