Answer to Question #160612 in Molecular Physics | Thermodynamics for Samychou

Question

If a gas is compressed isothermally, which of the following statements is true?
(a) Energy is transferred into the gas by heat
(b) No work is done on the gas
(c) The temperature of the gas increases
(d) The internal energy of the gas remains constant

Answer 1

Since the gas is compressed isothermally there is no change in temperature. As a result, the internal energy of the gas remains constant. Therefore, the correct answer is (d).

Answer:

(d) The internal energy of the gas remains constant.
