Answer to Question #160616 in Molecular Physics | Thermodynamics for Rashinda

Question

If a gas undergoes an Isobaric process, which of the following statments is true?
(a) the temperature of the gas doesn't change
(b) Work is done on or by the gas
(c) No energy is transferred by heat to or from the gas.
(d) The volume of the gas remains the same.

Answer 1

In an isobaric process the pressure of the system remains constant while the gas either expands or is compressed. As a result, the volume of the gas is changing and work is done on or by the gas. Therefore, the correct answer is (b).

Answer:

(b) Work is done on or by the gas.
