We relate the average mass n * of mobile particle clusters to the diffusion constant and the configurational entropy. Hence; n * can be interpreted as the mass of the “cooperatively rearranging regions” that form the basis of the Adam-Gibbs theory of the dynamics of supercooled liquids. We also examine the time and temperature dependence of these transient clusters.
