Consider 2.0 moles of N2 gas that undergo a reversible isothermal expansion at 250 K from 3.0 L to 5.0 L. Assume that the gas can be treated as ideal and that it has CV = 5R/2 and a molar mass of 28.01 g/mol. (a). (12 points) Calculate, in kJ/mol, the work, heat, internal energy change, and enthalpy change for the gas. Be sure to show all of your work, including units.
Two moles of an ideal gas undergo an isothermal expansion at 565 K from a pressure of 12.5 Bar to a final pressure of 1.50 Bar. Calculate AU, AH, and AS for the process if Cy = R. The same ideal gas undergoes an adiabatic expansion from the same initial pressure to the same final pressure (and the same initial temperature). Calculate the final temperature, AU, AH, and AS for the process.

Consider a reversible isothermal expansion of a gas at temperature τ from volume V to volume V + ∆V . This is not a monatomic ideal gas, but the internal energy of the gas is given by U(τ, V ) = a*V* τ^ 4 , where a is a constant. The pressure is p = (1/3 U)/V . (a) What is the change of energy of the gas in the expansion? (b) How much work is done on the gas...
