The given p−Vp-V diagram shows gases during adiabatic process. Plots 1 and 2 should correspond respectively to The given p-V diagram shows gases during adiabatic process. Plots 1 and 2 should correspond respectively to

Options

  1. AHe and O2\mathrm{O}_2
  2. BO2\mathrm{O}_2 and He
  3. CHe and Ar
  4. DO2\mathrm{O}_2 and N2\mathrm{N}_2

Correct answer

A. He and O2\mathrm{O}_2

Step-by-step solution

We know that (dpdV)=−γ(pV)∴\left(\frac{d p}{d V}\right)=-\gamma\left(\frac{p}{V}\right) \therefore \quad Slope ∝γ\propto \gamma From the Fig. (1), slope of 2>2\gt slope of 1 . So, plots 1 and 2 should correspond to He and O2\mathrm{O}_2 respectively.
