Air that initially occupies 049 m3 at a gauge pressure of, Ask an Expert

Academics

Air that initially occupies 0.49 m3 at a gauge pressure of 63 kPa is expanded isothermally to a pressure of 101.3 kPa and then cooled at constant pressure until it reaches its initial volume. Compute the work done by the air. (Gauge pressure is the difference between the actual pressure and atmospheric pressure.)
