What will be the specific heats of He at constant volume and constant pressure Gamma of He = - Physics - Kinetic Theory

Question

What will be the specific heats of He at
constant volume and constant pressure ? Gamma of He = 1
667 , R = 8 318 * 107 erg
mol-1 oC-1 ,
J = 4 18 * 107 erg
cal-1 and molecular mass of He
= 4

[ Answer : cv = 0 746 cal/g/ oC ;
Cp = 1 243 cal/ g/ oC ]

Dear Student,

Cp-Cv = R = 8
318 ×107  ---eq1 and CpCv  = γ =1
667 = 53⇒Cp =  53CV--------------eq2putting in eq1 53CV-Cv = 8
318 ×10723CV = 8
318 ×107CV =32× 8
318 ×107  = 12
477×107 erg /mol/oC   converting to cal/g/oCCV == 12
477×107 4×4 18 ×107  =0
746 cal/g/oCputting this value in eq2 Cp =53*0
746 =1 243 cal/g/oC
