Answer to Question #51926 in Field Theory for vi

Question

The difference between the principal specific heats of nitrogen is 300 J/kg °K and ratio of the two specific heats is 1.4. then the CP is
1050 J/kg °K
650 J/kg °K
750 J/kg °K
150 J/kg °K

CP
and
CV
denote the molar specific heats of a gas at constant pressure and at constant volume respectively. If and
CP/CV=γ,
then
CV
is equal to

R/(γ−1)

(γ−1)/R
