Carbon dioxide undergoes a process from state 1 at 640°R and 900 psia to state 2 at 900° R and 3000 psia. Estimate the change in enthalpy, internal energy, and entropy:
i) Assuming the carbon dioxide is an ideal-gas with constant specific heats from Table B-2E
ii) Using the ideal-gas tables in the Appendix
iii) Using the equations of Section 7.5
