An ideal gas (Cp=5.1926 kJ/kg/K, Cv=3.1156 kJ/kg/K) is placed in a piston-cylinder apparatus. The mass of helium is 5kg, and the initial temperature is 200K. The helium is heated by the surroundings, which remain throughout the process at a temperature of 300K, until the helium reaches thermal equilibrium with the surroundings. The pressure in the cylinder remains constant at 200 kPa. Draw a schematic and indicate your choice of system. What is the entropy change of the universe as a result of this process in SI units?
