When helium gas is allowed to expand into vaccum, heating effect is observed. The reason for this is (Assume He as a non ideal gas)

A

He is an inert gas

B

The inversion temperature of Helium is very high

C

The inversion temperature of helium is very low

D

He has the lowest boiling point

Text Solution

Verified by Experts

The correct Answer is:
C

Answer(3) The inversion temperature of helium is very low. Gases with low inversion temperature gets heated when allowed to expand in vacuum.
