Phase Transitions. Physics 313 Professor Lee Carkner Lecture 22. Exercise #21 Joule-Thomson. Joule-Thomson coefficient for ideal gas m = 1/c P [T( v/T) P -v] ( v/T) P = R/P m = 1/c P [(TR/P)-v] = 1/c P [v-v] = 0 Can J-T cool an ideal gas T does not change
Phase transitions. Qualitative discussion: the 1-component system water. Clausius-Clapeyron Equation. Heat Reservoir R. T=const. Consider a system of liquid & vapor phases in equilibrium at given P and T. P=const. vapor phase contains N 2 particles. constant # of particles. N=N 1 +N 2.
Phase Transitions. The above picture shows a block of solid Ar melting and subliming after exposur to aire at roughly room temperature. . http://en.wikipedia.org/wiki/Phase_transition . Phase Diagram of H 2 O. http://people.virginia.edu/~lz2n/mse209/Chapter9-p1.pdf.

Summary of the three States of Matter ALSO CALLED PHASES, HAPPENS BY CHANGING THE TEMPERATURE AND/OR PRESSURE OF A SUBSTANCE. GAS : total disorder; mostly empty space; particles have complete freedom of motion (vibrational, rotational, & translational); particles are very far apart.
