Growing plants then absorb this phlogiston, which is why air does not spontaneously combust and also why plant matter burns as well … Visa mer The phlogiston theory is a superseded scientific theory that postulated the existence of a fire-like element called phlogiston contained within combustible bodies and released during combustion. The name comes … Visa mer Empedocles had formulated the classical theory that there were four elements—water, earth, fire, and air—and Aristotle reinforced … Visa mer • Pneumatic chemistry – Very first studies of the role of gases in the air in combustion reactions Visa mer Eventually, quantitative experiments revealed problems, including the fact that some metals gained weight after they burned, even though they were supposed to have lost phlogiston.
