The limiting form of f(r, p, t) as t ~ 00 would then contain all the equilibrium properties of the system. The aim of kinetic theory therefore includes the derivation of the thermodynamics of a dilute gas. To fulfill this aim, our first task is to find the equation of motion for the distribution function. The distribution function changes with time, because molecules constantly enter and leave a given volume element in fL space. Suppose there were no molecular collisions (i.e., (J = 0). Then a molecule with the coordinates (r,p) at the instant t will have the coordinates (r + vSt,p + FSt) at the instant t + St, where F is the external force acting on a molecule, and v = p/m is the velocity. We may take St to be a truly infinitesimal quantity. Thus all the molecules contained in a fL-space element d 3 rd 3p, at (r, p), at the instant t, will all be found in an element d 3r' d 3p', at (r + v St, p + FSt), at the instant t + St. Hence in the absence of collisions we have the equalityDenso QR Bar Code barcode library on .netusing barcode drawer for .net vs 2010 control to generate, create qr barcode image in .net vs 2010 applications.f(r + vSt,p + FSt, t + St) d 3 r' d3v'Deploy qr code jis x 0510 on visual basic.netuse .net framework qr-code encoder todevelop qr code 2d barcode with vbwhich reduces to Control 3 of 9 image on javausing java todevelop 3 of 9 on asp.net web,windows applicationf(r, v, t) d 3 rd 3u Barcode creator on javausing barcode generator for java control to generate, create barcode image in java applications.(3.6)Control data matrix ecc200 image for javagenerate, create data matrix ecc200 none on java projectsf(r + v St, p + F St, t + St) = f(r, p, t)Connect ean13 in javagenerate, create gs1 - 13 none with java projectsbecause d 3 rd 3p = d 3 r' d 3p'. The last fact is easily established if we assume that the external force F depends on position only. At any instant t, we may choose d 3 r d 3P to be a six-dimensional cube. It is sufficient to show that the area of any projection of this cube, say, dx dpx, does not change. A simple calculation will show that this projection, originally a square, becomes a parallelogram of the same area in the time St, as illustrated in Fig. 3.2. This invariance is valid as long as (r, p) are canonically conjugate generalized coordinates. When there are collisions (i.e., (J > 0), equality (3.6) must be modified.

An explicit form for (at/ a coli can be obtained by going back to its t) definition (3.7). Consider Fig. 3.3, where the square labeled A represents the JL-space volume element at {r, p, t} and the one labeled B represents that at {r + v 8t, P + F 8t, t + 8t}, where 8t eventually tends to zero. During the time interval 8t, some molecules in A will be removed from A by collision. We regard A as so small that any collision that a molecule in A suffers will knock it out of A. Such a molecule with not reach B. On the other hand, there are molecules outside A which, through collisions, will get into A during the time interval 8t. These will be in B. Therefore the number of molecules in Bat t + 8t, as 8t ~ 0, equals the original number of molecules in A at time t plus the net gain of molecules in A due to collisions during the time interval 8t. This statement is the content of (3.7), and may be expressed in the form
