Question details

Consider a cylinder which contains 1 mole of a perfect. .(ideal) gas confined with a piston. The walls are all adiabatic. The system is originally in a state defined by Va and Ta Adiaba6c&enclosure vacuum Answer the following for a process in which in step 1 the system is allowed to expand irreversibly from ya to Vb.with an amount of work out W i. Is W1 the maximum work out that could be obtained? Why or why not? stive, negative or zero. ii. Is the change in S positive, negative or zero? What is.AS waveme iv. What is the change in temperature of the system in step 1 (in terms of Cv)? In the 2nd step for this process the gas is compressed reversibly and still adiabatically back to Va with work outW (be careful of sign here). v. At the end of this step is the temperature of the system higher, lower or the same as the original temperature before step 1.
