일반물리학 1 — The Kinetic Theory of Gases: Problem 49

49 Air that initially occupies \(0.280 \text{ m}^3\) at a gauge pressure of \(103.0 \text{ kPa}\) is expanded isothermally to a pressure of \(101.3 \text{ kPa}\) and then cooled at constant pressure until it reaches its initial volume. It then returns to its initial pressure in a constant-volume process. Compute the net work done by the air. (Gauge pressure is the difference between the actual pressure and atmospheric pressure.)
