You have a material (not unlike water) whose molar specific heat C, at atmospheric pressure is 30J/(mole K) in the gaseous phase, 75 J/(mole K) in the liquid phase, and 35 J/(mole K) in the solid phase. Furthermore, the material condenses at 373 K with a latent heat of 41 000 J/mole and freezes at 273 K with a latent heat of 6000 J/mole. Assuming that it behaves as an ideal gas at 600 K, find

(a) its enthalpy at 600 K,

(b) its molar enthalpy at 500 K, 374 K, 372 K, 323 K, 274 K, 272 K, and 200 K.

(At constant pressure, ΔH = ΔE + pΔV = ΔQ, so you don't have to worry about changes in volume at phase transitions.)
