Oil burning, an application of the laws of conservation of mass / energy

Oil burning, an application of: - Lavoisier's law of conservation of mass / matter (1789) which states that the mass of a closed system of substances will remain constant, regardless of the processes acting inside the system. An equivalent statement is that matter changes form, but cannot be created nor destroyed. This implies that for any chemical process in a closed system, the mass of the reactants must equal the mass of the products. and - The first law of thermodynamics (conservation of energy) which states that the increase in the internal energy of a system is equal to the amount of energy added by heating the system, minus the amount lost as a result of the work done by the system on its surroundings. In other words: energy can be transformed (changed from one form to another), but it can neither be created nor destroyed. The same amount of mass / matter / energy (from the Sun, the atmosphere, and Earth) needed to grow the life to produce the oil was released when it burned.
