If two gases have same reduced temperature and reduced pressure, then they will have the same

Solution (By Examveda Team)

According to law of corresponding states if two gases have same reduced temperature and reduced pressure than they will have same reduced volume.
Law of corresponding state: $$\left[ {Pr + \frac{3}{{{v_r}^2}}} \right]\left[ {3Vr - 1} \right] = 8R{T_r}$$
So, the answer is reduced volume.
