PHYS 445 Lecture 6 - Classical ideal gas 6 - 1 © 2001 by David Boal, Simon Fraser University. All rights reserved; further resale or copying is strictly prohibited. Lecture 6 - Classical ideal gas What's Important: classical phase space Text : Reif Classical ideal gas In the previous lecture, we introduced the concept of accessible states, with the number of accessible states in a given energy range E being defined as ( E ), related to the density of states ( E ) via ( E ) = ( E ) E . (6.1) As a first example, we evaluate ( E ) for a collection of classical non-interacting particles with only translational degrees of freedom. The energy of the system is [ energy of system ] = [ kinetic energy of all particles ] + [ potential energy of all particles ] + [ interaction energy between particles ] + [ mass energy ] or E = K + U + E int + Mc 2 . (6.2) For the classical ideal gas K = Σ i p i 2 / 2 m i [ potential energy of all particles ] = constant [ interaction energy between particles
