Thermochemistry Calorimetry Since we cannot know the exact enthalpy of the reactants and products, we measure H through calorimetry , the measurement of heat flow.

Thermochemistry Heat Capacity and Specific Heat The amount of energy required to raise the temperature of a substance by 1 K (1 ° C) is its heat capacity . We define specific heat capacity (or simply specific heat ) as the amount of energy required to raise the temperature of 1 g of a substance by 1 K.

Thermochemistry Constant Pressure Calorimetry Because the specific heat for water is well known (4.184 J/mol-K), we can measure H for the reaction with this equation: q = m × s × T
