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.
Answer & Solution
Correct Answer
(C) The inversion temperature of helium is very low
Step-by-step Solution
Detailed explanation
Hydrogen and helium exhibit heating effect during Joule Thomson expansion due to low inversion temperature.
