5. Sandler 6.28 (30 pts) For real gases the Joule-Thomson coefficient is greater than zero at low temperatures and less than zero at high temperatures. The temperature at which is equal to zero at a given pressure is called the inversion temperature. a. Show that the van der Waals equation of state exhibits this behavior, and develop an equation for the inversion temperature of this fluid as a function of its specific volume the cerrespending states form Tkinv=4V23(3V21)2
