Abstract: The heat of combustion (ΔH c 0 ) is the energy released as heat when a compound undergoes complete combustion with oxygen under standard conditions. The chemical reaction is typically a hydrocarbon reacting with oxygen to form carbon dioxide, water and heat. It may be expressed with the quantities: energy/mole of fuel (J/mol), energy/mass of fuel, and energy/volume of fuel. The heat of combustion is traditionally measured with a bomb calorimeter. It may also be calculated as the difference between the heat of formation (Δ f H 0 ) of the products and reactants. The heating value or energy value of a substance, usually a fuel or food, is the amount of heat released during the combustion of a specified amount of it. The energy value is a characteristic for each substance. It is measured in units of energy per unit of the substance, usually mass, such as: kJ/kg, J/mol, kcal/kg, Btu/m³. Heating value is commonly determined by use of a bomb calorimeter. The result for Cp is 2151.286982 cal/(grams˚C). Based upon specific heat the results are as follows: Para methyl-benzoic acid ΔHf(298)=1019213.578 cal, tetracosane ΔHcombustion=10623.31083 cal, tetracosane ΔHf(298)=3954475.689 cal, goldfish ΔHcombustion=4429.625753 cal, and goldfish ΔHf(298)=157936.3742 cal/moles.
