Many 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."
Joule-Thompson coefficient for methane
Joule Thompson effect. Gas going from high pressure to low pressure makes cooling effect. Same principle as your refrigerator.
yes,joule is a heating reversible effect .

Joule showed the heating effect due to the resistence of wire which cary the current.
Joule Effect. Jessie Andrews.
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.
That refers to heat being generated when a current flows through a resistor.
The symbol for Joule is "J"
The abbreviation of joule is simple J.Joule is a unit from SI.

I may be wrong, but kilo I think stands for 1000. Since a kilojoule is larger than a joule, I believe that you have to move the decimal point to the left. For example you would have less than 1 whole kilojoule in a joule, so it would be some thing like .00001 or something to that effect.
a joule is equal to a neton/metre
The joule is an SI unit!
Joule is a unit of work, and of energy.
2,346 Joule :)
Joule is the real name.

Oxygen and nitrogen can be liquified by compressing them, allowing them to cool to room temperature, then allowing them to re-expand (which chills them further due to the Joule-Thompson effect) and using the chilled gas to further cool the compressed gas. By repeating this cycle eventually the gas will drop below its boiling point and liquify.In practice, since oxygen boils at a higher temperature than nitrogen and liquid nitrogen is easy and relatively cheap to obtain, small amounts of liquid oxygen for lab use are generally prepared by allowing oxygen gas from a cylinder to flow through a coil submerged in liquid nitrogen.Helium is much more complicated, since it exhibits a negative Joule-Thompson effect at room temperature (it actually gets warmer upon expansion). It must be chilled down below about 50 K before it can be cooled further by expansion (and, since liquid nitrogen boils at about 77 K, you can't use liquid nitrogen to get gaseous helium cold enough to even start the Joule-Thompson process).
'J' is the abbreviation for the unit of energy - the Joule.
The Joule is the SI unit for energy.
