Question: The specific heat at constant pressure cp [J/(kg K)] of an ideal gas is related to enthalpy by where h = enthalpy (kJ/kg), and

The specific heat at constant pressure cp [J/(kg · K)] of an ideal gas is related to enthalpy by

Cp = dh dT

where h = enthalpy (kJ/kg), and T = absolute temperature (K). The following enthalpies are provided for carbon dioxide (CO2) at several temperatures. Use these values to determine the specific heat in J/(kg · K) for each of the tabulated temperatures. Note that the atomic weights of carbon and oxygen are 12.011 and 15.9994 g/mol, respectively
