If CP and CV denote the specific heats of nitrogen per unit mass at constant pressure and constant volume respectively, then?
If CP and CV denote the specific heats of nitrogen per unit mass at constant pressure and constant volume respectively, then
(a) CP – CV = 28R
(b) CP – V = R/28
(c) CP – CV = R/14

(b) : Molar heat capacity = Molar mass × specific heat capacity
So, the molar heat capacities at constant pressure and constant volume will be 28CP and 28CV respectively
Therefore, 28CP – 28CV = R or CP - CV = R/28.
