Critical scaling law

We return to binary solutions. In approaching their AG by the empirical method, we usually express the dependence of g on (f) and T by some analytical function. This operation is tin assumption, and is sometimes called the mean-field or classical approximation. It leads to the general prediction that the cloud-point curve in the vicinity of the critical point (Tc, 4>c) is described by a universal relation, called the critical scaling law ...
