When a gas is forced through an insulated,porus plug, this quantity is held constant.
In the Peng-Robinson equation, the departure function for this quantity is equal to R times criticaltemperature times a function of the compressibility factor. The change in this quantity is divided by negative2kt in the exponential of the expression giving the density of Schottky defects in a crystal. Both this quantityand the mass flow rate are held constant along a Fanno line. When a gas is forced through an insulated,porus plug, this quantity is held constant. For an ideal solution, the (*) change in this quantity upon solvationis zero. This quantity, which is held constant during a Joule-Thomson process, is equal to the internal energy pluspressure times volume. The fact that this quantity is a state function leads to Hess' Law. The change in this quantitydetermines whether a reaction is endo or exothermic. For 10 points, name this quantity symbolized H.
In the Peng-Robinson equation, the departure function for this quantity is equal to R times criticaltemperature times a function of the compressibility factor.
