There is 0.5kg of perfect gas kept in a cylinder covering by a cover.If it is heated in a reversible non-flow constant pressure process from 288k to 368k,the heat required is 50kJ ..If it is heated in a reversible non-flow constant volume process between the same temperatures,the heat required is 38kJ.Determine Cp,Cv of the gas.

✔ 最佳答案
Cp = ΔH/m*ΔT= Q/m*(T2-T1)
= 50/0.5*80
= 1.25 kJ/kg.k * 1/4.2 kcal/kJ
= 0.2976 kcal/kg.k
Cv = ΔU/m*ΔT
= 38/0.5*80*4.2
= 0.26619 kcal/kg.k
