Today (December 31, 1691) is Memorial Day to Robert William Boyle, the world's first modern chemist, famous for Boyle's law.

Today (December 31, 1691) is Memorial Day to Robert William Boyle, the world's first modern chemist, famous for Boyle's law.

Robert William Boyle was born on January 25, 1627, in Ilyismore, Waterford, Ireland, the fourth child of Richard Boyle and Catherine Benton. Richard Boyle came to Ireland from England in 1588 after being appointed deputy manager of the Tudor estates in Ireland. Robert William Boyle was born at a time when Richard Boyle was a landowner. He was raised in an Irish family background like his older brothers when he was a child. Boyle learned Latin, Greek and French through private school. He lost his mother when he was eight.

Boyle's father's friend, Sir Henry Wotton, was sent there because he was a teacher at Eaton College in England. During this time his father hired Robert Carey, a private instructor, to teach Robert William Boyle the Irish language. However, he was not interested in the Irish language. After spending three years in Eaton he went abroad with a French instructor. In 1641 they visited Italy. Galileo Galilei, who lived in those days, stayed in the province of Florence in the winter to learn about the contradictions of the big stars.

Boyle is an alchemist. Believing that there was an opportunity to change more metals he experimented in an attempt to achieve it. And French scientists came up with a piston (like the needle we put in). When the piston was pressed to one side, it was pressurized by the gas inside and the piston tried to return to its old position. But could not do so. So French scientists set out to prove that the gas pressure is not equal. Boyle alone said the test was not correct. He said the pressure on the gas would remain the same, except that the piston could not be put back into the same position by the gas because it was too hard. He also challenged that he would make such a piston in a few days and prove his point.

Two weeks later he picked up an English ‘U’ shaped tube. One side of it was three feet taller than the other. The taller part was thinner and the lower part was thicker and the upper part of the thicker part was stuffed. Boyle poured mercury through one of these tubes. Mercury was poured into both tubes until slightly elevated. Thus a certain amount of air is trapped in the blocked area. The piston is a technique for trapping air. Boyle said it was a piston now that the air was trapped here as well. On the mat, where the mercury was now, he again poured some mercury from this side.

Now the air in that area was compressed and the mercury rose to a little more height. Boyle, now marking the location of the mercury, again expelled the mercury through a valve at the bottom of the tube. Now again the mercury came back to the old place and stopped. Boyle thus proved that the air pressure was equal. He also found that the capacity of the air changes negatively according to its weight. That is, if you lift three parts of the weight, one-third of the space is filled with air. Many scientific advances have been made through this rule.

The Ideal Gas Law

Boyle is considered the world's first modern chemist. Who laid the foundation for modern chemistry. One of the pioneers of the modern experimental scientific method. He became famous for Boyle's law that when the temperature of a gas in a closed system does not change, its relationship between pressure and volume is inversely proportional. Boyle's law describes how gases behave when subjected to pressure on a volume. At this constant temperature, the pressure of a given mass of gas and its volume are inversely proportional. It was discovered in 1662 by a scientist named Robert Boyle. Mathematically,

P ∞ 1 / V, (at constant temperature) or

PV = k, (a constant)

The pressure is P1 when the temperature is T and the volume of the gas is V1. According to this rule if the gun volume of the gas at the same temperature is V2 and its pressure is P2

Let P1V1 = P2v2 = constant.

The Skeptical Chemist is considered a textbook in the field of chemistry. Boyle, one of the founders of the Royal Society, was elected Fellow of the Royal Society (FRS) in 1663. Robert William Boyle, the world's first modern chemist, became famous for Boyle's Law on December 31, 1691, at the age of 64 in London, England. Boyle's Law is given after his name.
