The gas expands adiabatically, but non-equilibrium, from the initial equilibrium state 1 to the final, also equilibrium, state 2. In this case, the gas does some work. The gas is then quasistatically compressed to initial state 1: first isothermally, then adiabatically. The work expended during compression turned out to be greater than the work done by the gas during expansion by the amount A = 20 J. The temperature of the gas T in state 2 is 250 K. Find the change in the entropy of the gas during the transition from state 1 to cos
