A graph of pressure P in pascals versus volume V in cubic meters. The horizontal axis represents Volume V, scaled from 0 to 4 in increments of 1. The vertical axis represents Pressure P, scaled from 0 to 700 in increments of 100. Point X is located at V = 1.0, P = 200. Point Y is located at V = 3.0, P = 600. A straight diagonal line segment with an arrow pointing from X to Y connects the two points. The region under the line segment down to the horizontal axis between V = 1.0 and V = 3.0 is lightly shaded. No other labels, lines, text, or axes appear.
Pressure versus volume graph for the gas expansion.
A sample of an ideal gas expands from state \(X\) to state \(Y\) along a straight diagonal path on the \(PV\) diagram shown. During this process, the gas pressure increases linearly from \(200 \text{ Pa}\) at a volume of \(1.0 \text{ m}^3\) to \(600 \text{ Pa}\) at a volume of \(3.0 \text{ m}^3\). How much work is done by the gas on its surroundings during this expansion?
