Oxygen gas is compressed in a piston-cylinder device from an initial state of 0.8 m^3/kg and 45 C to a final state of 0.1 m^3/kg and 287 C. Assume the oxygen is an ideal gas with constant specific heats. The ideal gas constant is R = 0.2598 kJ/kgK and the specific heat is Cy = 0.69 kJ/kgK. In the question that follows, select the answer that is closest to the true value. What is the change in entropy during this process in units of kJ/kgK?

Question
Oxygen gas is compressed in a piston-cylinder device from an initial state of 0.8 m^3/kg and 45 C to a final state of 0.1 m^3/kg and 287 C. Assume the oxygen is an ideal gas with constant specific heats. The ideal gas constant is R: 0.2598 kJ/kgk and the specific heat is Cy = 0.69 kJ/kgK. %3D In the question that follows, select the answer that is closest to the true value. What is the change in entropy during this process in units of kJ/kgK?
