When an ideal undergoes unrestrained expansion, no cooling occurs beca – InterviewSolution

1.	When an ideal undergoes unrestrained expansion, no cooling occurs because the molecules
Answer» are above the inversion temperature exert no attraction FORCE on each do work equal to LOSS in kinetic energy collide without loss of energy. Solution :When an IDEAL gas undergoes expansion, no work is done in OVERCOMING attractive forces. Hence internal energy does not fall and hence temperature also does not fall
