# Question #6a366

For $J m o {l}^{-} 1 {K}^{-} 1$, R is a linear scaling factor of energy content of 1 mole of ideal gas. The energy increases linearly with temperature.
${m}^{3} P a . {J}^{-} 1 {K}^{-} 1$also exist since the energy term can also be derived in terms of pressure and volume by relating to its momentum change (read this link )
