The grаph shоws pressure аs а functiоn оf volume for sample of an ideal gas. The gas has an internal energy of 1000 J at state X and is taken through the cycle shown. Process 3 is isothermal. The work the gas does on the environment is 400 J during process 1 and 250 J during one complete cycle. What is the net thermal energy transferred into the gas during one complete cycle? The horizontal axis is volume and the vertical axis is pressure. A point labeled X lies at higher pressure and lower volume on the left. From X, a horizontal line labeled 1 extends right to a top-right corner. From that point, a vertical line labeled 2 goes downward to a lower right corner. A curved path labeled 3 returns from the lower-right point back to X, concave up.
