Answer to Question #98656 in Physical Chemistry for Abhishek

Question

What are the dimensions of R ?

Answer 1

R is a so-called Gas Constant, which means the work required for one mole of the ideal gas to be expanded when it is heated on one degree of the Kelvin scale. This work is equal to 8.314 $\frac{J}{mol*K}.$ Precisely, in SI units it possesses the following dimensions - $kg*m^2*s^{-2}*mol^{-1}*K^{-1}.$
