Joule-Thomson co-efficient is defined as__________________?
Correct answer: B. μ = (∂T/∂P)H
- A. μ = (∂P/∂T)H
- B. μ = (∂T/∂P)H
- C. μ = (∂E/∂T)H
- D. μ = (∂E/∂P)H
Explanation
The Joule-Thomson coefficient measures the temperature change with pressure during an isenthalpic process, so μJT = (∂T/∂P)H. The reciprocal derivative (∂P/∂T)H is not the usual Joule-Thomson coefficient.
