WebCalorimetry (Q = mc T) Calorimetry is a way to measure the heat change of a chemical reaction. A very simple way to do this is shown below. For example, you could add HCl and NaOH to the beaker and measure the temperature change. NaOH + HCl The big problem with this kind of basic set up is heat loss. A beaker is not an ideal container as it is ... WebCALORIMETRY 3. 1 In an experiment, 0.750 g of benzene (C6H6) were completely burned in air. The heat evolved raised the temperature of 200 g of water by 43.7 43.7°C. Use this data to calculate the enthalpy of combustion of benzene (the-1 -1 specific heat capacity of water is 4.18 J g K ).
