The phlogiston theory states that the every combustible substance contains phlogiston. When a combustible substance is burned, phlogiston is released into the air. The people behind the 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. Without phlogiston, the combustible substance won’t be able to start fire.
In the late 1660’s a scientist named as Johann Joachim Becher tried to explain the phlogiston theory. He thought that the every substance has a different kind of earth. The earth names which he gave to substances are combustible, verifiable and the mercurial. He believed that the burning of combustible substance causes “combustible

After meeting with Priestly, Lavousiere tried to experiment on mercury. He heated the mercury, until it turned into powder form. When the mercury gets heated, it absorbs the air from the surroundings. Lavousiere measured the air which mercury absorbed and then he heated the powdered form of the mercury in order to turn the mercury into its previous form. Lavousiere also measured the amount of air released by mercury powder when heated. He found out that the amount of air absorbed by mercury when it heated is the same as the amount of air released when mercury powder is heated.
In the same year, 1774, Lavousiere announced that he has discovered the gas known as oxygen. The people living at that time were quite impressed by his work. But Lavousiere made a big mistake by not giving credit to Priestly. Priestly was quite unhappy from Lavousiere because he didn’t gave a credit to his ideas. However, some people think that Lavousiere should get the credit for the discovery of oxygen due to the fact that he understood it better and gave it the right name. His determination towards the discovery of oxygen also makes other people to support him and his discovery. In my opinion, although Lavousiere discovered the oxygen, but he should give credit to Priestly and to Stahl and Becher as well because these three people contributed a lot towards the development of phlogiston
The Armenian genocide ruins Vahan Kenderian’s picture-perfect life. Vahan is the son of the richest Armenian in Turkey and before the war begins, he always has food in his belly and a roof over his head in the book Forgotten Fire by Adam Bagdasarian. Life is absolutely quintessential for Vahan, until the war starts in 1915, when he endures many deaths of his family, losses of his friends, and frightening experiences in a short amount of time. He is a prisoner of war early in the book and is starved for days. As he goes through life, he is very unlucky and experiences other deaths, not just the deaths of his family. Vahan ultimately becomes the man his family would want him to be.
For the first phenomena, he noted how all combustions involved the formation of fire or light. With that in mind, Lavoisier also observed that this combustion occurs only through dephlogisticated air / pure air. Other airs (e.g. carbon dioxide) act as a fire extinguisher similar to that of water. Another combustion phenomenon he outlined was how the weight of the burnt material directly relates to the amount of air used in the reaction. Moreover, he also described how certain substances turn into acids after it has been burn...
. Open your book to page 125. Research paintings by Italian artist Giuseppe Arcimboldo. This painting “The Four Elements - Fire” is an allegory of fire. What lesson or message does the painting seem to suggest about the meaning of fire? (1 paragraph). The painting “The Fire” by Giuseppe Arcimboldo is made of fire, candles, rifles, and different materials such as sticks and what looks to be turquoise. This painting to me gives off the feeling of a strong warrior or just something very hot and strong. The use of everyday objects put together to create a human looking face brings together a picture that means more as if a person was made of fire, candle holders, and guns creating the illusion of a portrait.
The first two acts of this film are truly inspiring because they capture the "fire" of the environmental movement. It chronologically begins by discussing the origins of conservative environmentalists, to documenting the details of successful environmental movements, and concluding by explaining the merging of civil rights with environmentalists. Ultimately, “A Fierce Green Fire “serves as a dynamic call for the continuing action of protecting and conserving our biosphere.
Catching Fire: How Coooking Made us Human by Richard Wrangham is a fresh perspective on the evolution of humankind. Wrangham has made a concentrated effort to prove that humans have evolved particular adaptations, like bipedalism, due to the introduction of cooked foods into their diet. In his book, he is legitimately arguing that humans are the way they are because early on in human evolution, early man discovered fire, discovered the joys of cooked foods, and developed all sorts of fascinating traits still being utilized today.
In 480 BC the Persian Empire was once again trying to invade ancient Greece. Under the reign of King Xerxes, an invincible army of a recorded 2 million was marching downwards to enslave all Greeks. An elite force of three hundred Spartans tackled the suicide mission of stalling the Persian wave of doom.
A book that fully illustrates the hardships of dealing with the reconstruction of a nation after an era of slavery as well as concisely providing insight to a strong civil rights voice is “The Fire Next Time” by James Baldwin. His writing is a both an examination of race relations in a segregated America, and an impassioned plea for both whites and blacks to abandon the hate and embrace love as an outlet for their differences. The title of the book comes from an negro spiritual quotation that Baldwin directly relates to the inevitable consequences of continuing racial injustice: "God gave Noah the rainbow sign, No more water, the fire next time!"
March 25th 1911 is the day one of the largest deadly workplace fires occurred. 146 factory workers died on this day as they fought to escape the Triangle Shirtwaist factory only to find locked exits, and faulty fire escapes. The public witnessed this display of poor fire safety and was quickly filled with sorrow. William Gunn Shepard claimed, “I remember their great strike of last year, in which these girls demanded more sanitary workrooms, and more safety precautions in the shops…. These dead bodies told the result.” This fire is often referred to as the tragedy that awakened the consciousness of America. The Triangle Fire showed the public the horrific working conditions that thousands of employees had at the time. The death of these 146
Joseph Priestly was the first to begin studying the effects of nitrous oxide. Joseph Priestly was an influential chemist whom throughout history contributed to many great strides in the study of chemistry. Headed by Joseph Blacks discovery that gases were substances in their own right and Hales apparatus to find gas over water Priestly sought out to report on gases. Priestley made N2O by heating ammonium nitrate in the presence of iron filings, and then passing the gas that came off (NO) through water to remove toxic by-products8. Priestley discovered NO, NO2, N2, HCl and N2O (all in 1772), O2 (1774) and SO(J.R Parington). Black reported on O2 s calling it nitrous air diminished. Priestley’s goal was to report upon gases, soon after this was accomplished Priestly moved on leaving further discovery of O2 in the hands of his future colleagues.
Accepting change can be both hard and scary. With change comes discomfort, insecurity, and the possibility of negative results. Although younger generations have an easier time adjusting to and accepting the ever-changing world in ways such as technology, education, and what is to be considered ‘typical’, older generations seem to have a tougher time breaking from tradition and giving new things a try. Four authors discuss the difficulty some have of accepting change through poetry, song, and informative articles, and the impact it has on society or an individual. At first their writings may seem unrelated. However, although the formats, stories, and directions are different, there is one thing in which they become strongly unified; the particular pieces of literature all uniquely share a common theme that shows
2 - Phlogiston theory - 17th - 18th century - taught that every substance that burns contained a mysterious ingredient called "Phlogiston". It was later shown to be oxygen.
The immense power of a text is gained through the distinctive ideas portrayed within. Through his poetry John Foulcher, Australian poet and teacher, outlines his observations of the environment surrounding him and the conflict within it. These poems include ideas such as the brutality of nature trumping its beauty, as represented in the poems For the Fire and Loch Ard Gorge. As well as how observing nature's savagery can give insight into human mortality, as prominently expressed in Loch Ard Gorge, and lastly the complexity of society compared to the divinity of the natural world, demonstrated in Summer Rain. The distinctive ideas portrayed in these texts create powerful meaning and affect those reading them, allowing others to learn more about
Book XII of the Metaphysics opens with a clear statement of its goal in the first line of Chapter One: to explore substances as well as their causes and principles. With this idea in mind, Chapter One delineates the three different kinds of substances: eternal, sensible substances; perishable, sensible substances; and immovable substances. The sensible substances are in the realm of natural sci...
The understanding that matter was composed of atoms was changed with the discovery of smaller particles than the atoms, which are protons, neutrons, and electrons. But during the 1960’s, the multitude of particles being discovered was making the understanding that matter is composed of protons, neutrons, and electrons, insufficient. Murray Ge...
Fire begins with an idea of a spark. Then the spark is made and with the
