First Law of Thermodynamics

Easy
For an ideal gas, the value of the Joule-Thomson coefficient is
- Apositive
- Bnegative
- zero
- Dindeterminate
Explanation
For an ideal gas, enthalpy depends only on temperature, so throttling (constant enthalpy) produces no temperature change. The Joule-Thomson coefficient μ_JT = (∂T/∂p)_h is therefore zero for an ideal gas.
