5 kg of air is heated from an initial state of 37C and 101.33 kPa until its temperature reaches 237C . Calculate AU, Q, W and AH for the following processes : (a) Isochoric process. (b) Isobaric process. Air is assumed to be an ideal gas. We are given that Cp = 29.1 J/mol-K Cy = 20.78 J/mol-K = Molecular weight of air = 29
