The phlogiston theory has been debunked by the discovery of oxygen. When materials burn, they combine with oxygen, not phlogiston as believed in the theory. The understanding of combustion and oxidation provided by oxygen led to the rejection of the phlogiston theory.
One piece of evidence for the phlogiston theory was the observation that combustion released a substance called "phlogiston" from burning materials, leaving behind ash. Another piece of evidence was the weight gain of metals when they were heated in air, which was believed to be due to the absorption of phlogiston. However, the theory was eventually disproven with the discovery of oxygen and the understanding of oxidation.
Support for the phlogiston theory came from observing that substances such as wood and charcoal released a substance (phlogiston) when burned, leaving behind ash. This was believed to explain the weight loss during combustion. Additionally, the theory was used to account for the process of rusting in metals.
The phlogiston theory was widely held in the 17th and 18th centuries to explain combustion and oxidation. However, it was eventually disproven with the discovery of oxygen by Lavoisier. This discovery provided a more accurate explanation for the process of combustion.
Antoine Lavoisier is credited with rejecting the phlogiston theory. Through his experiments and observations, he was able to show that combustion involved a process of oxidation rather than the release of phlogiston. This led to the development of modern chemistry.
The concept of phlogiston was unsatisfactory because it failed to explain observations in chemistry, such as the increase in weight of metals when they rusted or burned. It was eventually replaced by the theory of combustion with oxygen based on more experimental evidence.
No, it was not. The phenomena explained by the theory are now known to be a result of oxidation, and phlogiston does not exist.

Antoine Lavoisier disproved the phlogiston theory by experimenting with combustion reactions and showing that burning substances gained weight instead of losing it. He demonstrated that oxygen is an essential component of combustion, not phlogiston as proposed by the theory. Lavoisier's precise measurements and meticulous approach to experimental evidence played a crucial role in discrediting the phlogiston theory and establishing the foundation for modern chemistry.
The phlogiston theory of burning is an outdated concept that suggested a substance called "phlogiston" was released during combustion. It was believed that the presence of phlogiston was necessary for materials to burn. However, this theory has been disproven with the advancement of modern chemistry, which identifies combustion as a process involving the reaction of materials with oxygen in the air.
because it changed their mind to belive that phlogiston is in flammable things.
Proposed the theory of burning called the phlogiston theory

1. I believe that theories can only be disproven, not proven. i.e. You create a theory and then you try to disprove it, if you can't then you can consider that theory to be true (convicing other people may be more difficult however). 2. I think the theory you describe is disproven as and todays equivalent is what we now know as 'oxidation'.
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.
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.
It is a process that involves oxygen. The phlogiston theory has been disprooven for a long time.
