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
1 answer
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, which suggested that all combustible materials contained a substance called phlogiston that was released during combustion, was once widely accepted. However, it has since been discredited with the advancement of modern chemistry and the discovery of oxygen's role in combustion. Today, the phlogiston theory is considered a historical scientific misconception.

The Phlogiston theory was unable to explain certain chemical reactions, such as the combination of metals with oxygen. It also lacked experimental support and was eventually replaced by the more accurate oxygen theory of combustion. Additionally, the concept of phlogiston was found to be vague and arbitrary.
1 answer
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.

The phlogiston theory was proposed by German chemist Georg Ernst Stahl in the 17th century. Stahl believed that phlogiston was a substance released during combustion.
2 answers
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.

Proposed the theory of burning called the phlogiston theory
1 answer
The phlogiston theory of burning is an outdated concept that suggested a substance called "phlogiston" was released during combustion.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.
1 answer
Some scientists disagreed with the phlogiston theory because it could not explain all the observations, such as the weight changes in substances during combustion. Additionally, the discovery of oxygen and its role in combustion provided a more accurate explanation for the phenomena previously attributed to phlogiston.
1 answer
No, Antoine Lavoisier did not agree with the phlogiston theory. Instead, he proposed the modern understanding of combustion, which involves the reaction of a substance with oxygen. His experiments led to the rejection of the phlogiston theory in favor of the oxygen theory of combustion.

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.

The alchemist and physician J. J. Becher proposed the phlogiston theory
The 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 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.
1 answer
Phlogiston can be defined as "a hypothetical substance once believed to be present in all combustible materials and to be released during burning." Chemistry was so underdeveloped at the time Antoine Lavoisier gained interest in it that it could hardly be called a science. The prevailing view of combustion was the Phlogiston Theory which involved a weightless or nearly weightless substance known as phlogiston. Metals and fire were considered to be rich in phlogiston and earth was considered phlogiston poor. The following were the main theories put forward for 'phlogiston': * Weight loss when combustibles are burned because they lose phlogiston * Fire burns out in an enclosed space because it saturates the air with phlogiston * Charcoal leaves very little residue when burned because it is made mostly of phlogiston * Animals die in an airtight space because the air becomes saturated with phlogiston * Some metal calxes turn to metals when heated with charcoal because the phlogiston from the charcoal restores the phlogiston in the metal

The Pholgiston theory explains that when substances (feul) burn, people belived that pholgiston (oxygen) is produced leaving behind the Clax (ash)
1 answer
It was noticed that when things burn, they often leave behind an ash or residue that doesn't burn. It was suggested that before it burns, a flammable object contains some substance called phlogiston, which would make it burn, and when the phlogiston is used up, what is left over would not be able to burn. This theory was later shown to be wrong, and phlogiston is no longer part of the science of chemistry.
1 answer
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.
1 answer
The facts, as they stand, are these: every creature, when respiring, releases phlogiston. In fact, respiration is simply to be considered a form of combustion. Anything that can burn contains phlogiston. Substances, when burnt, release this weightless, invisible substance - an element of their being, their composition - the phlogiston. The phlogiston is always in need of somewhere to go. Such as, air is best for the phlogiston. Air can absorb it. Taking this mode of thinking to its furthest logical conclusion we can only state that the reason creatures "suffocate" is because there is nowhere for the phlogiston to go. When air was removed from around a living creature then there is nowhere for the phlogiston to go and so respiration would cease and the creature dies.

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.

Back when Chemistry was still pretty much Alchemy, people tried to understand fire in terms of what must be escaping from burning material. This "stuff" was phlogiston. Today we understand fire in terms of what's being added to the burning material, namely Oxygen.
The thing about the Theory of Phlogiston was that it was elegant; that is, it was simple, yet it explained everything. Wood burned readily because it had a lot of phlogiston; rock had very little; water had none. It was not until people tried to extract and measure phlogiston that they began to suspect there was a little problem with the idea.
The story of phlogiston supplies a good cautionary lesson that something can be very reasonable and yet not be true.

The phlogiston theory was discarded by chemists a long time ago. The idea was that things burn because they contain some mysterious substance called phlogiston, and when the plogiston is used up, what is left is an ash of some sort which can no longer burn. We now know that combustion involves many different chemical reactions that different flammable chemicals have, rather than being the result of one single flammable substance that is present in everything that burns. Combustion does always involve oxygen, but oxygen can react with a great many different chemicals.

The theory holds that all flammable materials contain phlogiston, a substance without color, odor, taste, or mass that is liberated in burning. Once burned, the "dephlogisticated" substance was held to be in its "true" form, the calx.
"Phlogisticated" substances are those that contain phlogiston and are "dephlogisticated" when burned; "in general, substances that burned in air were said to be rich in phlogiston; the fact that combustion soon ceased in an enclosed space was taken as clear-cut evidence that air had the capacity to absorb only a definite amount of phlogiston. When air had become completely phlogisticated it would no longer serve to support combustion of any material, nor would a metal heated in it yield a calx; nor could phlogisticated air support life, for the role of air in respiration was to remove the phlogiston from the body."[4] Thus, phlogiston as first conceived was a sort of anti-oxygen.
Joseph Black's student Daniel Rutherford discovered nitrogen in 1772 and the pair used the theory to explain his results. The residue of air left after burning, in fact a mixture of nitrogen and carbon dioxide, was sometimes referred to as "phlogisticated air", having taken up all of the phlogiston. Conversely, when oxygen was first discovered it was thought to be "dephlogisticated air", capable of combining with more phlogiston and thus supporting combustion for longer than ordinary air.[5]

Phlogiston is a hypothetical substance which at one time was thought to be the basis of combustion, but which is now known to be fictitious. It is not an element.
