Carbon dioxide $($CO$2)$ is heated from $450$ K to $650$ K at atmospheric pressure.

Determine the enthalpy change $(\backslash$Delta h$)$ using:

a$)$ Ideal gas tables $($A$-23)$

b$)$ The empirical specific heat equation $($A$-21)$

c$)$ Average specific heat $($A$-20)$

d$)$ Specific heat at starting temperature
