Enthalpy
The enthalpy of a material in a certain range of temperature and pressure is well approximated by the expression:
H = A + BT + CP + DT2 + EP2 + FTP
1. Is this expression for H an approximation to the fundamental relation, or is it an equation of state. Explain your answer for credit.
2. Calculate the specific heat at constant pressure, cP, within the approximation for H given above.
