where does the energy from fire come from
Fire Fire is hot because the conversion of the weak double bond in molecular oxygen, O2, to the stronger bonds in the combustion products carbon dioxide and water releases energy (418 kJ per 32 g of O2); the bond energies of the fuel play only a minor role here.[2] At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma.[3] Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different.
Olympic flame The idea for the Olympic flame was derived from ancient Greece, where a sacred fire was kept burning throughout the celebration of the ancient Olympics on the altar of the sanctuary of Hestia.[2][3] In Ancient Greek mythology, fire had divine connotations â€” it was thought to have been stolen from the gods by Prometheus. Sacred fires were present at many ancient Greek sanctuaries, including those at Olympia. Every four years, when Zeus was honoured at the Olympic Games, additional fires were lit at his temple and that of his wife, Hera. The modern Olympic flame is ignited at the site where the temple of Hera used to stand.
