6) Expansion of a perfect gas into vacuum is related with(1) ΔΗ(2) q – InterviewSolution

1.	6) Expansion of a perfect gas into vacuum is related with(1) ΔΗ(2) q 0(3)W=0(4) All of these
Answer» When an Ideal gas is expanded into vacuum, it does no work. (W =0) Hence, no change in the internal energy and thus in the temperature of the gas.This means the q = 0, change in internal energy and enthalpy are also zero.Hence, Option (4) is correct.
