Question

Which of the following statements are true? Heat is converted completely into work during isothermal expansion. Isothermal expansion is reversible under ideal conditions. During the process of isothermal expansion, the gas does more work than during the isobaric expansion (at constant pressure) between the same initial and final volumes.

Answer 1

Answer:

Heat is converted completely into work during isothermal expansion

Explanation:

first law:

• ΔU = Q + W

∴ ΔU = CvΔT = 0....isothermal

⇒ Q = - W
