Extracted text: A rigid vessel of 0.06 m3 volume contains an ideal gas, CV = (5/2)R, at 500 K and 1 bar. a. If heat in the amount of 15,000 J is transferred to the gas, determine its entropy change. b. If the vessel is fitted with a stirrer that is rotated by a shaft so that work in the amount of 15,000 J is done on the gas, what is the entropy change of the gas if the process is adiabatic? What is AStotal? What is the irreversible feature of the process?
