An ideal gas is expanded isothermally from 20 L to 30 L. During this process, 6 J of energy is expended by the external mechanism that expanded the gas. Which of the following statements is correct?

Question

Quizplus · Accepted Answer

During an isothermal expansion, the internal energy of an ideal gas remains constant, so the work done by the external mechanism (6 J) must be compensated by an equal amount of heat flowing into the gas from the surroundings to maintain its temperature.
