Fuel is a substance that reacts with oxygen to produce useful energy.
What is energy output?
The amount of energy resulting from combustion of a fuel is referred to as energy output. The amount of energy produced from the fuel's combustion reaction depends on the amount of substances present in the chemical reaction.
What is molar heat combustion?
The amount of energy produced by fuels can be measured. Specific energy (mass) and energy density (volume) are measures of energy content.
