... electromagnetic system. The surface integral of Eq. 6.84 can be thought of as the total momentum flowing into our volume through the surface per unit time. Alternatively one might think of it as being the electromagnetic “force” exerted on our volume by the outside world. The second term on the left ...

... strictly to the limit T = 0, but it is a valid approximation so long as, let us say, p/kT is very large. Now V is of the order of 5 volts and kT is 8 6 X 10- T in the same units. This is sufficient to guarantee the observed independence of T for all ordinary temperatures. The form of the exponent xZ ...
