Enthalpy divided by temperature
WebAnswer: Enthalpy is the part of the Free Energy of a reaction/change which determines if a reaction releases energy (exothermic) or absorbs energy (endothermic). Some reactions mixtures get warmer as they react (exo-) some get cooler (endo-). Diluting concentrated sulphuric acid in water is an ex... WebHeat capacity C describes the amount of heat required to change the temperature of a substance: C = By definition, the heat capacity of water at 15°C is 1 cal K-1 g-1 or 18 cal K-1 mol-1 (i.e., the heat required to heat 1 gram of water from 14.5 to 15.5°C is 1 calorie). Heat capacities of solids approach zero as absolute zero is approached: C = 0
