The phlogiston theory of combustion:(Greek word phlogiston means <u><em>"BURN"</em></u>)
Phlogiston theory states that phlogisticated substances are the substances that contain phlogiston and dephlogisticate when burned.
Dephlogisticating is the process of releasing stored phlogiston,which is absorbed by the air.
Growing plants then absorb this phlogiston,which is why air does not spontaneously combust and also plant matte burns as well as it does.
The prevailing theory was that flammable materials contained a substance called phlogiston that was released during the combustion.
For example:
- phlogiston was transferring into the surrounding air.
