The Phlogiston Theory in chemistry explained the presence of phlogiston in combustible materials, which was later disproven due to various observations.
The Phlogiston Theory was a theory in chemistry that explained combustible materials as containing phlogiston, a substance released during burning. It posited that combustible bodies lost phlogiston during combustion, with the remaining residue termed as calx.
