(sp_heat of water = 4 J/g×°C) Δthot = 28 °C - 40 °C = -12 °CCalorimetry is a method of determining heats of reaction. The heat generated by a reaction causes the temperature of a solution to rise. By measuring this temperature change, and relating it to the heat capacity, one can find the amount of heat generated in a reaction. A “calorimeter” is an insulated device in which the reaction is carried out.
