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).
use the T=2a/(bk) equation shown in the first link, plugging in a and b values found in the second link. proofs are shown in the joule-thomson expansion wikipedia page as well as the van der waals equation of state page.
if all other factors remain constant (pressure and moles) then the temperature goes up proportionately. (assuming the ideal gas law.)

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).

Joule showed the heating effect due to the resistence of wire which cary the current.

yes,joule is a heating reversible effect .
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.
