(a) Calculate q, w, AU, AH, and AS when 1 mole of an ideal monatomic gas is compressed isothermally and reversibly from 1 bar to 5 bar at 500K. Assume Cv = 3/2 R. Hint: You cannot calculate these five values in their order listed above. Choose a more convenient order. (b) Calculate q, w, deltaU, deltaH, and deltaS when the gas changes between the same two conditions, but irreversibly, such that it now requires twice as much work to do the process.
