Learning Goal Internal Energy of an ideal gas The internal energy of a system is the energy stored in the system. In an ideal gas, the internal energy includes the kinetic energies (translational and rotational) of all the molecules, and other energies due to the interactions among the molecules. The internal energy is proportional to the Absolute Temperature T and the number of moles n (or the number of molecules N). n monatomic ideal gases, the interactions among the molecules...

Repeat Problem 3, but this time, treat the steam as an ideal gas with cp = 2.083 kJ/kg-K, which is its value at about 700 K. (You will need to determine Rg = Ru/MWwater, with MWwater = 18.0 kJ/kg-K, as well as k = cp/cv). You’ll find that the ideal gas model is not too bad for water vapor under these conditions.
