Joule-Thomson co-efficient is the ratio of________________?
Correct answer: B. Temperature change to pressure change occuring during adiabatic throttling of a gas
- A. Pressure change to temperature change occuring during adiabatic compression of a gas
- B. Temperature change to pressure change occuring during adiabatic throttling of a gas
- C. Temperature change to pressure change occuring during adiabatic compression of a gas
- D. Pressure change to temperature change occuring during adiabatic throttling of a gas
Explanation
The Joule-Thomson coefficient is μJT = (∂T/∂P)H, measured during throttling, which is normally adiabatic and isenthalpic. It is therefore temperature change divided by pressure change during adiabatic throttling, not compression.
