1. Assuming that water vapor behaves as an ideal gas with six degrees of freedom per molecule, what is the enthalpy of one mole of water vapor at 500 "C and 3 atm?
2. At room temperature (295 K) and atmospheric pressure (1.013 x 105 Pa) estimate the number of air molecules in a room 8 m by 10 m by 3 m and the average separation between the molecules.
