This produces a decrease in temperature and results positive JouleThomson coefficient. It follows that for the Z JouleThomson coefficient will be negative and gas gets warmer. Chemistry Questions Tags Users Badges Unanswered Ask Reason for negative Joule Thomson coefficient of Helium and Hydrogen NTP conditions up vote down favorite Recently while reading my textbook came to know that Neon are the only gases which have . This requires energy which has to be supplied by the internal of gas. This in part due to changes kinetic energy but there another contributed by nonideality of gas

Graphic. Second our process is carried out as follows gas at pressure flows into region of lower without significant change kinetic energy. In general at low temperature Z and PV will increase the gas expands resulting positive JouleThomson coefficient. This can thus lead to increase temperature and the JouleThomson coefficient will be negative. Temperature is constant adiabatic phase so this condition gives us one more important information about experiment
