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 are plotted as under Which of the following order of volume is correct?

Options

  1. AV 4 > V 3 > V 2 > V 1
  2. BV 1 > V 2 > V 3 > V 4
  3. CV 1 = V 2 = V 3 = V 4
  4. DV 2 > V 1 > V 3 > V 4

Correct answer

B. V 1 > V 2 > V 3 > V 4

Step-by-step solution

At constant temperature T, V ∝ 1 P (for 1 mol gas). Thus, correct sequence of volume will be V 1 > V 2 > V 3 > V 4
