SUMMARY
The discussion focuses on calculating the work done by air when inflating a balloon, governed by the pressure-volume relationship P = CV³, where C is 100 kPa/m³. The work done, W, is determined by integrating the pressure over the change in volume from 1 m³ to 3 m³. The calculated pressures at these volumes are P1 = 100 kPa and P2 = 900 kPa. The integral W = ∫PΔV is essential for finding the area under the pressure-volume curve, which represents the work done.
