The phlogiston theory proposed that everything contains an element called phlogiston which is released when something burns. It was initially challenged by the fact that things do not necessarily lose weight when burned.
It was replaced entirely by oxidation theory (which we still hold today) when it was realised that things could not burn if oxygen wasn't present.

∙ 14y agoThe phlogiston theory has been proven incorrect. Chemists now realize that there is no specific element that is found in all flammable things. Instead, the ability to burn has something to do with reaction to oxygen in the air.

∙ 15y agoit was quite a beautiful theory except for the fact that it didn't explain a few heat related phenomena. It was finally proven wrong by Priestly I believe when he should heat could be produce by purely mechanical means, in particular boring out cannon mussels.

∙ 13y agoIt was first thought that phlogiston was a substance, or gas rather, that was secreted from a combustion reaction. It was also thought that when the air became highly concentrated with phlogiston that the reaction would cease. However, this was later disproved by Lavoisier, who discovered that the reason combustion reactions ceased was because of the lack of oxygen. Oxygen, in fact, used to be called dephlogisticated air.

4t + 6O = 37873873489. 98H the atoms simply can't handle the exmourumeothicology gas. which is the phlogiston theory

How did Antoine lavoisier disprove the phlogiston theory?
There was no evidence until at least 2 yrs into the work of the phlogiston theory
Did Antoine lavoisier agree with the phlogiston theory?
The Phlogiston theory was before it waslearned that matter burns by using oxygen. Most chemists looked to explain combustion as the release of an unknown substance, which they named "phlogiston". Phlogiston theory was a conceptual breakthrough that helped chemists conduct experiments and share ideas.
What is a scientific explanation for a range of hypothesis and observations supported by testing?
i have no clue i also want that answer for homework
What primary difference between a scientific theory and a hypothesis is that a theory is?
A scientific theory is more elaborated than a simple hypothesis and generally is validated by experiments.
Why do you think our current of atomic structure is well accepted as a scientific theory but is not a scientific law?
In science, "theory" is the name applied to well-established scientific knowledge. It doesn't mean that there are doubts about the atomic theory.
Who rejected phlogiston theory?
Lavoiser rejected the phlogiston theory!
Is phlogiston considered a scientific knowledge?
No. Phlogiston was a theory considered to be fact and actually hindered scientific knowledge until it was discredited. The theory was used to explain certain observations about flame, oxidation, and the formation of certain compounds, most noticeably cinnabar. As with some theories, phlogiston used variable factors to explain anomalies. For instance it was assumed to have negative weight under certain circumstances. Once oxidation was properly understood phlogiston theory was no longer considered true.
How many people believed in the phlogiston theory?
Most people in the scientific community accepted it in the 18th century.
Is it possible to change a scientific theory?
yes. the Phlogiston theory of combustion is no longer considered correct. The same is true of the Geocentric theory of the Solar system, or of the Flat Earth theory.
Is Phlogiston considered not to be scientific knowledge?
Phlogiston was an early scientific attempt to explain what is now referred to as the generation and flow of heat. It was believed to be a fluid that existed inside objects and could flow through them (even if they were solids)). It was replaced by the theory of thermodynamics.
When iron rusts is it a phlogiston theory or a oxygen theory?
It is a process that involves oxygen. The phlogiston theory has been disprooven for a long time.
Was the phlogiston theory of burning correct?
No, it was not. The phenomena explained by the theory are now known to be a result of oxidation, and phlogiston does not exist.
Who propose the phlogiston theory?
The phlogiston theory was first proposed by Johann Joachim Becher in 1667. This theory is now considered obsolete and was replaced by the oxygen theory.
How did Antoine lavoisier disprove the phlogiston theory?
There was no evidence until at least 2 yrs into the work of the phlogiston theory
What is the phlogiston?
The alchemist and physician J. J. Becher proposed the phlogiston theoryThe phlogiston theory (from the Ancient Greek φλογιστόν phlogistón "burning up", from φλόξ phlóx "flame"), first stated in 1667 by Johann Joachim Becher, is an obsolete scientific theory that postulated the existence of a fire-like element called "phlogiston", which was contained within combustible bodies and released during combustion. The theory was an attempt to explain processes of burning such as combustion and the rusting of metals, which are now collectively known as oxidation.
What are the good points of the phlogiston theory?
a combustible material is made up of 2 parts: the calx and phlogiston when a substance burnt the phlogiston into air and calx(ash) left behind so there are no good points of this theory
Why did the phlogiston theory change peoples ideas about burning?
because it changed their mind to belive that phlogiston is in flammable things.
