32) where R is the gas constant, CV is the, presumed constant, heat capacity at constant volume, and c is a constant independent of all thermodynamic state variables. Taking the partial derivatives of S(E,V) we ind that ( ∂ ∂E )V = CV E and ( ∂ ∂V )E = nR V . 33) E = CVT. 32) encapsulates the physics of an ideal gas. 30) on mixed partial derivatives. Working backwards But how, in the irst place, are entropy functions produced? One way to produce an entropy function S(E,V) is to work backwards from known equations of state by integrating (∂S/∂E)T = 1/T and (∂S/∂V)E = P/T.

In the Système International all other kinds of temperatures are deined as linear functions of kelvin temperatures. Translation from one kind of temperature to another is straightforward. For instance, to convert 23 degrees Celsius to kelvin we simply add 273 to 23 and produce, to three-place accuracy, 296 K. And to convert 68 degrees Fahrenheit to Celsius, we subtract 32 from 68 and multiply the result by 5/9 to produce 20 degrees Celsius. 16) in terms of absolute temperature. 17) that is, T g (TC ) T H g (TH ).

Is the multiplicity Ω of this N macrostate and (1 2 ) is the probability of any one microstate of this macrostate. A few empirical tests for small values of N suggest that the value of n that maximizes P(n) is approximately N/2 – in which case the two chambers have equal numbers of particles. A more systematic derivation of this result is possible when the numbers of particles in the two chambers, n and N − n, are so large as to be effectively continuous variables, that is, when n 4 1 and N − n 4 1.
