Joule Thomson Effect
</dt>
The decrease in temperature which takes place when a gas expands through a
throttling device as a nozzle. Also called Joule-Kelvin effect.
</dd>
The rate of change of temperature T with pressure p in the
Joule-Thomson effect is called the Joule-Thomson coefficient (symbol μ):
Joule-Thomson effect to take place the gas must initially be below its inversion temperature; if above the inversion temperature, the gas will gain heat on expansion. The inversion temperature of hydrogen, for example, is approximately -183 degrees C. </dd>
