T.4 - Joule Thompson EffectT.4 - JOULE THOMPSON EFFECT
A highly compressed CO2 gas at room temperature is allowed to expand through a thin metal nozzle. The decrease in temperature os the gas is evidenced by the dry ice formed around the nozzle. The collong effect can also be demonstrated by projecting the reading of an electrometer connected to the thermocouple onto the screen.
