Question

The pressure P for a gas is plotted against its absolute temperature T for two different volumes V₁ and V₂. If P is plotted on y-axis and T on x-axis, then

Easy

Solution

$PV = nRT; PV \propto T; V \propto \frac{T}{P}$
Slope of the graph $\frac{P}{T}$ so volume is inversely proportional to slope
${Tanθ}_{1} > {Tanθ}_{2} ∴ V_{2} > V_{1}$
