Q3/ A cylinder fitted with a frictionless piston contained an ideal gas, with a volume of 23 m², a temperature of 17 °C, and a pressure of 2 bar. It asks to raise its pressure to 6 bar by two different reversible processes: Heating under constant volume and cooling under polytropic compression with n=1.3. Determine the work and heat as well as entropy change of ideal gas for two processes. Knowing that: Cp = 0.293 kJ/kg.K Cv = 0.24 kJ/kg.K. 4
