The ideal gas equation for 1 mol of ideal gas is& PV = nRT The graph between P and T at constant volume, i.e. isochores

Which of the following order of volume is correct?

Options

  1. AV4>V3>V2>V1{V}_{4} > {V}_{3} > {V}_{2} > {V}_{1}
  2. BV1>V2>V3>V4{V}_{1} > {V}_{2} > {V}_{3} > {V}_{4}
  3. CV1=V2=V3=V4{V}_{1} = {V}_{2} = {V}_{3} = {V}_{4}
  4. DV2>V1>V3>V4{V}_{2} > {V}_{1} > {V}_{3} > {V}_{4}

Correct answer

B. V1>V2>V3>V4{V}_{1} > {V}_{2} > {V}_{3} > {V}_{4}

Step-by-step solution

At constant temperature T, V∝1PV ∝ \dfrac{1}{P} (for 1 mol gas).
Thus, correct sequence of volume will be
V1>V2>V3>V4{V}_{1} > {V}_{2} > {V}_{3} > {V}_{4}
