https://doi.org/10.32446/0132-4713.2020-3-43-52
Abstract
The influence of the gas presence in calorimeter on the result of measuring of thermal capacity is considered. The feature of the case is the unavoidable change of the gas mass during measuring procedure. The correct expression for the value of amendment is obtained, and uncertainty is evaluated for the calorimeter КА-С4 that serves as the standard of the unit of heat capacity.
