Question 39 of 190

For a perfect gas, two pressures ${P}_{1}$ and ${P}_{2}$ are shown in figure. The graph shows

Show answer and solution

Answer: (A) ${P}_{1}\gt {P}_{2}$

We know that the ideal gas equation of gas is

PV=nRT

Keeping the temperature constant, we have,

V\propto \dfrac{1}{P}

As seen from graph,

{V}_{2}\gt {V}_{1}

, so

{P}_{1}\gt {P}_{2}
