Calculate the heat capacity per unit mass of air at constant volume and the heat capacity per unit mass of air at constant pressure. Assume that air has a temperature of 300 K and a pressure of 1.00 times 105 N/m2. Also, assume that air is composed of 74 percent N2 molecules (molecular weight 28.0 g/mol) and 26 percent O2 molecules (molar mass of 32.0 g/mol) and that both components are ideal gases. cV = J/kg · K Compare your answer for the specific heat at constant pressure to the value listed in the Handbook of Chemistry and Physics of 1.032 kJ/kg · K.Explanation / Answer
a. 0.72116
b 1.00854
c. change in Cv=0.366%, change in Cp=0.404%
