CiteSeerX Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda) The heat theorem (ie the second law of thermodynamics or the existence of entropy) is a manifestation of a general property of hamiltonian mechanics and of the ergodic Hypothesis In nonequilibrium thermodynamics of stationary states the chaotic hypothesis plays a similar role it allows a unique determination of.

The two equations agree when the average translational kinetic energy of the molecules is K av = (3/2)kT Here we have a fundamental connection between temperature and the average translational kinetic energy of the atoms they are directly proportional to one another Temperature is a measure of the average kinetic energy of the atoms.

We study supernovadriven galactic outflows as a mechanism for injecting turbulence in the intergalactic medium (IGM) far from galaxies To this aim, we follow the evolution of a 1013M⊙ galaxy along its merger tree, with carefully calibrated prescriptions for star formation and wind efficiencies.

I've already told you multiple times that big, uppercase U is the internal energy of a system And it's really everything thrown in there It's the kinetic energy of the molecules.
