Why not use joules for measuring combustion
2006-06-14 01:38:35 · update #1
because in the process of combustion energy is released and calories are the measurement of that energy. they're doing nothing - they just show the amount of energy produced from burning something

Combustion is an exothermic process, meaning heat is released. Heat is a form of energy, and one way energy can be measured is in calories.

because in the combustion process bonds break up and enery is released
frm the law of conservation of energy this energy is transformed in other forms

Energy is stored in the form of potential chemical energy contained in the links between atoms of the burning substrate.
Combustion is combining with oxygen and energy generally is released in the form of heat or may be captured in other chemical forms.
