... by water is q= MC?T. Where q is the heat absorbed, m is the mass of the water, ?T is the change in temperature of the water and C is the specific heat of the water or 4.184J/g° C. By carefully measuring the change in temperature of the water we can calculate the amount of heat that is absorbed by the water. The heat absorbed by the water is equal to the amount of heat given off by the reaction. If q is positive, heat is gained and is an endothermic reaction (energy is required); if q is negative, heat is lost (energy is released) it is exothermic reaction. A calorimetry is an experimental method used to investigate heat flow. The heat flow that is investigated can be the result of either a chemical change or a physical change. The equipment used to perform the measurement of heat flow ...
