Claude's liquefaction process employs the cooling of gases by__________________?
Correct answer: C. Expansion in an engine
- A. Throttling
- B. Following a constant pressure cycle
- C. Expansion in an engine
- D. None of these
Explanation
Claude's process obtains cooling mainly through expansion in an engine, where the gas performs work and its temperature falls. This distinguishes it from the Linde process, which relies primarily on throttling.
