Express measurements of thermal activity in the melting region
Abstract
Express measuring procedures for determining the thermal activity of substances in the phase transition region are presented, with reference to experimental results for ethylene glycols. The effect of such factor as the temperature dependence of thermophysical characteristics and the heat of the phase transition is estimated in the context of a plane problem. It is shown that the kinetics of the phase transition significantly effects the results of express measurements.
