It is an experiment in which the Joule-Thomson coefficient is measured. Basically, you are expanding a gas under adiabatic conditions to ensure constant enthalpy and you will notice that there will be a temperature change (most likely cooling).

∙ 15y agoMany materials exhibit the "Thompson effect;" when a current passes through certain materials, one end becomes cooler and one becomes hotter. This relation is given with a simple equation using a mu as the Thompson coefficient.
The effect is often referred to as the "Joule-Thompson Effect."

Also, is important in the liquefaction of gases, as it tells whether a gas cools or heats on expansion

Joule Thomson effect is temperature dependent or not?
its temperature dependent
What is the real name of JJ Thomson?
Sir. Joseph John Thomson. Sir. Joseph John Thomson.
When was Jim Thomson's house build?
Jim thomson's house was built in 1959.
Why does the can of dust off get cold?
Joule-Thomson effectAlso known as the Joule-Kelvin effect. When a Gas expands through a porous plug, a change of temperature occurs, proportional to the pressure difference across the plug. The temperature change is due to a departure of the gas from Joule's Law, the gas performing internal work in overcoming the mutual attractions of the Molecules and thus cooling itself; and partly to deviation of the gas from Boyles law. The latter effect can give rise to either to cooling or heating, depending upon the initial temperature and pressure difference used. For a given mean pressure, the temperature at which the two effects balance, resulting in no alteration of temperature, is called the inversion temperature. Gases expanding through a porous plug below their inversion temperature are cooled, otherwise they are heated.
What subatomic particle was first discovered?
This particle was the electron in 1897 (J.J. Thomson).
What are the applications of joule Thomson effect?

Joule Thomson effect is temperature dependent or not?
its temperature dependent
What is the value of joule Thomson coefficient for Natural gas?
Joule-Thompson coefficient for methane
How joule Thomson experiment lead to coefficient?

What is physical significance of joule's constant?
It is the mechanical equivalent of heat.
Who found heating effect of electric current?
Joule showed the heating effect due to the resistence of wire which cary the current.
Is joules heating effect-a reversible effect?
yes,joule is a heating reversible effect .
Why does a helium tank get colder as you let out more helium?
Letting gas out of a cylinder always causes a cooling. This is the Joule-Thomson effect. As the gas expands work is done against the interatomic/molecular attractions (dispersion forces for helium).
Why do hydrogen and helium get having very low temperatures warmed up instead of cooling in joule-thomson method?
There is for every gas a point called the inversion temperature. Above this temperature, the gas exhibits a reverse Joule-Thompson effect and warms on expansion instead of cooling. The inversion temperatures for hydrogen and helium are quite low compared to those of most other gases.
The working of thermocouple is base upon the principle called?
Thomson effect
