A gas in a cylinder piston system occupies V, - 15 mºat P. = 220 kPa and T, -20°C. Then, the gas undergoes a polytropic compression process until its temperature becomes T, 300'C. The entropy change of the gas during this process is AS - -1.7626 kJ/K, (AS-S.-5.). By assuming ideal gas (R = 0.3 kJ/kg.K. cp = 0.8 kJ/kg.K. cv = 0.5 kJ/kg.K), determine: 3pt) the mass of the gas, m (kg) = (9pt) the work transfer, W (kl)...
