You have an ideal gas in an insulated container. The volume of the container increases from 10 m3 to 20 m3 under a constant pressure of 50. × 105 Pa. What was the work done on the gas?
We will use the formula W = PΔV. We know that ΔV = 10, P = 50. × 105 Pa. We plug these values in and get W = PΔV = 5.0 × 107 J.
