Use the following diagram to answer the next problem. An ideal heat engine uses 0.01 mol of gas and operates between a hot reservoir at
T H = 400 K and cold reservoir at T L = 300 K, in a cycle from a→b→c→d→a. From a→b the gas undergoes an isothermal expansion, changing its volume from Va to 2.5Va. From b→c, the pressure is reduced at a constant volume. From c→d, the gas undergoes an isothermal compression, and from d→a, the pressure is increased at a constant volume until the gas is back at the original condition at a.

-How much heat is absorbed in going from a$\to$b?

Quizplus · Accepted Answer

The heat absorbed in going from aF1F1F1S1F1F1F10b is equal to the difference in energy between the two states. The energy of aF1F1F1S1 is -30.5 J, and the energy of F1F1F10b is -22.9 J. Therefore, the heat absorbed is 30.5 J - 22.9 J = 7.62 J.
