Phlogiston theory
The phlogiston theory states that the every combustible substance on this planet contains phlogiston. When a combustible substance is burned, phlogiston is released into the air. The people behind the phlogiston theory believed that the whenever a substance sets on fire, the fire gives off phlogiston. The phlogiston was believed be the kind of gas which causes fire.

So, when a metal is heated, the metal starts to change into its metallic oxide so, during that process phlogiston is released. The theory presented by Stahl was not reliable because it created misconceptions. For example, when a material is burned, the weight of the ash of burned organic materials is always less the actual weight of the organic material. But when metal is heated to convert it into calx. The weight of the calx is always more than the actual weight of the metal. Although, Stahl’s idea was a bit complexed and unreliable, but his idea contributed a lot towards the development of the phlogiston …show more content…
For example, when a candle burns it gives off phlogiston. The phlogiston keeps on building up inside the jar and there comes a time when there is no room left for phlogiston. So, the candle flame will go out. If noxious air is present in the jar then the candle flame will go out faster. Same will happen if a mouse is trapped inside the jar. The mouse will release off phlogiston as he breathers and phlogiston will start to build up inside the jar and after some time the jar will be fully filled up phlogiston thus, causing the mouse to

    Beside the concerns of combustion and calcination, Lavoisier claimed that the matter of fire played a great role in explaining the states of gases, liquids and solids. He suggested that whether something is a gas, liquid, or solid depended on the amount of the matter of fire that could affiliate with it. He concluded that liquids and vapors/gases had much more of the matter of fire while those in the solid state contained very little of it or none at all. Therefore, in order for a material to catch fire, pure air must be present since the matter of fire within it contributes to the formation of a…

    The article I had chosen came from the magazine Astronomy and it titled “How moon dust will put a ring around Mars.” Phobos, one of the larger martian moons is making its way towards Mars and will eventually hit the gravitational line of Mars. The force will break apart this moon and in result, Phobos will turn into boulders, rocks ,and dust orbiting Mars. Pieces of the moon that do not fall into the orbit will end up crashing into the surface of Mars, causing more craters. This is predicted to happen twenty five to seventy five million years from now, but Mars will end up having its own ring system like the gas giants.…

    Prion infectious diseases: History and molecular pathology It is circa 500 BC, and Hippocrates records rare but localised outbreaks of madness within livestock; he observes that the animals’ neurological capabilities rapidly decline after years of apparent normality. When he investigates, he finds that the brains of these animals are ‘very full of dropsy and of an evil odour’. He hypothesises that this disease would be able to spread and infect humans too (McAlister, 2005). To him, this is obviously not a product of Gods like the common ideas of infection at the time, instead he describes it as ‘organic’. It is 1755, farmers in Britain watch their sheep go into hysteria, rubbing their hind-quarters against fenceposts and rocks until they…

By the end of the rotation however, I did end up gaining at least some valuable experience and insight that I did not receive in my previous work experience.…
