(a) True

(b) False

I got this question during an interview for a job.

I'm obligated to ask this question of Thermodynamics Applications topic in section Thermodynamics of Chemistry – Class 11

Answer 1

Right option is (a) True

Explanation: The expansion of a gas in a vacuum without pressure is called free expansion. During the free expansion of gas, the work is not done whether the process is reversible or Irreversible. So the above statement is considered to be true.
