A gas expands from A to B as shown in the graph.Calculate the work (in joules)done by the gas.(1 atm= 1.01 × 10⁵ N/m². )

Question

Quizplus · Accepted Answer

The work done by the gas is given by the area enclosed under the curve on a pressure-volume graph. In this case, the area is a trapezoid with base 2 L and heights of 1 atm and 2 atm. Therefore, the area is ((1 atm + 2 atm)/2)*2 L = 1.5 atm*L = 1.5*(1.01 × 10S1U1P15S1S1P0 N/mS1U1P12S1S1P0)*10S1U1P-2S1S1P0 mS1U1P3S1S1P0 = 2.42 × 10S1U1P16S1S1P0 J.
