Heat capacity measurement

WebModulated DSC (MDSC®) is an accurate method to measure heat capacity (and specific heat capacity Cp) of materials. Proper experimental conditions are required in order to obtain best results. There are two ways to determine Cp on a Differential Scanning Calorimeter (DSC) using MDSC. WebFor example, to measure the specific heat capacity of copper, one would need a calorimeter (a small cup) made of copper, and of known mass. Pour a measured mass of boiling water (100 °C) into this. The temperature of the copper rises from room temperature, t 1 °C, to a final temperature, t 2 °C, while the temperature of the copper falls from 100 …
