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

Options

  1. AO 2 and H e
  2. BH e and O 2
  3. CH e and A r
  4. DO 2 and N 2

Correct answer

A. O 2 and H e

Step-by-step solution

We know that d p d V =   - γ   p V ∴             S l o p e   ∝ γ From the fig. (i), slope of 2 > slope of 1.So, plots 1 and 2 should correspond to O 2 and H e respectively. [ γ He = 5 3   ,  γ 0 2 = 7 5 ]
