a sample of 1.00 mol perfect gas molecules at 300K and 1 atm with Cp,m=7R/2 is put through the following cycle: (a) constant-volume heating with twice its initial temperature, (b) reversible, adiabatic expansion back to its initial temperature, (c) reversible isothermal compression back to 1.00 atm. Calculate q, w, delta U, and delta H for each step.
