WITH AN ACCURACY OF  104

UDC 536.22

A method of measuring small ( 10-4) relative 
changes in the thermal activity of liquids is developed. 
A theoretical substantiation of its accuracy is given based 
on an investigation of the factors responsible for errors 
in the experiment. Results of experiments on a study of the 
temperature dependence of the thermal activity of a solution 
of polystyrene in toluene are reported.
