Determining Specific Heat of Filling in Measuring Kettle

2 Determining Specific Heat of Filling in Measuring Kettle 

There exist three possibilities to determine the heat capacity C2 respectively the specific heat Cp of filling within the measuring kettle 

The filling G in the measuring kettle is brought to the temperature T2 by the short-term action of the electric heater, and then the temperature decrease T2 t) T2o = AT(f) is recorded. Because of (6.1) and (q-physicochemicai + 9physicai) = 0, the reaction runs corresponding to 

Plotting ln AT(0) versus time gives as a result a straight line with the slope 

Between the specific heat Cp and the effective heat capacity C2, the relation Cp = C2 — CmJ/G holds. Combining this with (6.7) we obtain
