All physical theories are based on a certain set of balance equations. Their derivation varies from the variational methods to the a priori statements. We adopt in this paper an approach suggested by M.E.Gurtin, W.Noll and W.O.Williams (see, for instance, M.E.Gurtin, W. O. Williams1967) and based on the axioms of continuity, As an example, we consider the scalar balance equation.
