kinetic theory

[kə′ned·ik ′thē·ə·rē]
(statistical mechanics)
A theory which attempts to explain the behavior of physical systems on the assumption that they are composed of large numbers of atoms or molecules in vigorous motion; it is further assumed that energy and momentum are conserved in collisions of these particles, and that statistical methods can be applied to deduce the particles' average behavior. Also known as molecular theory.

It is a hasty generalization that since the caloric theory was surpassed by the kinetic theory, the kinetic theory will also be surpassed by a hitherto unconceived alternative.

Compared to collision frequency obtained by calculation using kinetic theory derived expressions, the expression used by [10] gives collision frequencies which are close to the ones determined from S-parameters, thus 5.82 x [10.sup.10] and 6.37 x [10.sup.10] rad [s.sup.-1] for the temperatures 1006 and 839 K, respectively.
