In an ideal gas equation which is constant?

Step-by-step solution

According to ideal gas equation, pV = nRT where, p = pressure, V = volume n = no. of mole, T = temperature R = universal gas constant R =8.314 ~J ~mol ⁻¹ ~K ⁻¹=0.08205 ~L ~atm ~mol ⁻¹ ~K ⁻¹=1.99 cal mol ⁻¹ ~K ⁻¹=5.189 10¹⁹ eV mol ⁻¹ ~K ⁻¹
