Express your answer in joules. W = 2.1×104 J Submit Previous Answers Part C Correct The work done in a process is the area under the curve in the pV diagram. The work done by the gas is positive since the volume increases. The magnitude of the work is the area under the curve: W = (2.0 × 105 Pa + 5.0 × 105 Pa)(0.070 m³ – 0.010 m³) = 2.10 × 10¹ J VO How much heat had to be put in during the process to increase the internal energy of…
