Combustion, rapid chemical reaction of two or more substances with a characteristic liberation of heat and light it is commonly called burning. Heat of combustion heat of combustion (δh° c) is the measure of the amount of energy released in the form of heat (q) when one mole of a substance is burned ()the production of heat means the reaction is an exothermic process and gives off energy. If 5 g of glucose (c 6 h 12 o 6) with a molar heat of combustion of 255 x 10 3 kj/mol is burnt under a container holding 250g of water at 25 o c, and no heat is lost to the external environment, what is the rise in temperature of the water.
Combustion is a rapid chemical reaction between fuel and oxygen when combustible elements of fuel combine with o 2, heat energy comes outduring combustion combustible elements like carbon, sulfur, hydrogen etc combine with oxygen and produce respective oxides. Combustion fundamentals the heating value, a measure ofthe heat release during complete combustion, is also reported with the ultimate analysis.
