A. Joule Thomson effect is the change in pressure that accompanies the expansion of a gas without the production of work or transfer of heat. B. Joule Thomson effect is observed only in gases at extremely low temperatures. C. Joule Thomson effect is not applicable to the liquefaction of gases. D. Joule Thomson effect the change in temperature that accompanies expansion of a gas without production of work or transfer of heat, at ordinary temperature and pressure all real gases except hydrogen and helium cool upon such expansion, this phenomenon often is utilized in liquefying gases. « Previous Next »
