Joule-Thomson co-efficient which is defined as, η = (∂T/∂P)H = 1/Cp (∂H/∂T)P, changes sign at a temperature known as inversion temperature. The value of Joule-Thomson co-efficient at inversion temperature is ___________________?
Correct answer: A
Explanation
At the inversion temperature, the Joule-Thomson coefficient becomes zero. This is where the relationship between temperature and pressure changes sign.
