| Abstract: | Principle and experimental process to determine the continuous heat capacity of material by differential scanning calorimetry (DSC) were introduced. Continuous heat capacities from 310K to 370K of benzoic acid standard sample and three polypropene heat- isolating material samples were determined by DSC method. The differences between the heat capacity values determined by experiment and that reported in literature of benzoic acid were not more than 0.02J/(K.g). The deviations between two repeated experimental results of three polypropene heat isolatating material samples were not more than 0.03 J/(K.g). |
