Air undergoes a process from state 1 at 220 K and 200 kPa to state 2 at

Question:

Air undergoes a process from state 1 at 220 K and 200 kPa to state 2 at 300 K and 10 MPa. Estimate the change in enthalpy and entropy:
i) Assuming the air is an ideal-gas with constant specific heats from Table B-2
ii) Using the ideal-gas tables in the Appendix
iii) Using the equations of Section 7.5
iv) Using the IRC Calculator
