ABSTRACT
Reports on the development of a new method that fits the whole temperature response of a heat-pulse calorimeter for heat capacity. Analyzation of the thermal response of a heat-pulse calorimeter on a model that was used by the relaxation method to derive some useful relations and further utilize the numeric method of the general linear least squares to determine the heat capacity of a sample; Accuracy of the proposed method which was verified by determining the heat capacity of a 0.249 76 g copper sample; Comparison of the result with the literature; Indication that the proposed method is capable of measuring heat capacity regardless if the sample is adiabatically or nonadiabatically isolated; Details of the employed calorimetric system.
