Under isobaric heating gas to ΔT1 = 100 K is required Q12 = 4,2 kJ of heat, and at isochoric cooling gas gives Q23 = 5,04 kJ of heat at a low pressure twice. The initial temperature of the gas at the isochoric cooling T2 = 400 K. Draw graphs of these processes in the coordinates of P - V. Determine Poisson´s ratio for the gas. Find the entropy change ΔS gas for each of izoprotsessov and for the whole process.
