One mole of diatomic ideal gas at an initial pressure of 10 atm is allowed to expand against the surrounding at a constant external pressure of 1 atm, coming to equilibrium at5 1 atm. the temperature remains constant at 300 k. calculate delta u and w for the process and use the first law to determine q. what is delta s_surroundings? next, calculate delta s by considering a reversible path that connects the same initial and final states. is delta s universe positive? now calculate delta a and find the maximum work that could have been extracted from this same change in state had the process been carried out reversibly?
