Webwhere mm is the mass of the substance and cc is the specific heat capacity of a substance. You can find specific heat capacity for different substances in Table 5.2.1 on this page. ΔTΔT will determine the sign of the heat of the reaction (qq). If ΔT is positive, qq is positive and the reaction is exothermic. WebCalculate the heat lost by the warm water and the heat gained by the cold water (mass H 2 O * ∆T * specific heat.). You can assume that the density of water is 1.0 g/mL, and the specific heat of water is 4.184 J/g ˚C. The result simply measures the amount of heat required to raise the
