Question

Cp and Cv denote the molar specific heat capacities of a gas at constant pressure and constant volume respectively . Then

Answer 1

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

(d) CP – CV = R
