Final answer:
The term for the total energy released when a specific amount of fuel is burned is 'Heat of combustion', which is measured as the molar heat of combustion in a bomb calorimeter.
Step-by-step explanation:
The term that describes the total amount of energy released when a specific amount of fuel is burned is Heat of combustion. When fuels combust, chemical energy that is stored within the bonds of the substance is converted into heat (thermal energy). The molar heat of combustion indicates the amount of heat released when one mole of a substance undergoes complete combustion. The measurement of this energy is commonly carried out in a bomb calorimeter, where the fuel is burned in an excess of oxygen, and the resulting temperature increase in water or another surrounding material is measured to calculate the energy released.
