Two kg of air initially at 2 MPa and 800°C in a closed system expands in a reversible, isothermal process to 250 kPa. There are negligible changes in potential and kinetic energies, and air can be assumed as an ideal gas with constant specific heats. For the process described above: a) W=Q b) W = AU AU=0 Q=0 Q=AU c) W=0 d) None of the above Two kg of air initially at 2 MPa and 800°C in a closed system expands in a reversible, isothermal process to 250 kPa.
