Robert Boyle Robert Boyle Robert Boyle (; 25 January 1627 – 31 December 1691) was an Anglo-Irish natural philosopher, chemist, physicist, and inventor. Boyle is largely regarded today as the first modern chemist, and therefore one of the founders of modern chemistry, and one of the pioneers of modern experimental scientific method. He is best known for Boyle's law, which describes the inversely proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept constant within a closed system. Among his works, "The Sceptical Chymist" is seen as a cornerstone book in the field of chemistry. He
Gas the volume is doubled, the pressure is halved. Given the inverse relationship between pressure and volume, the product of pressure ("P") and volume ("V") is a constant ("k") for a given mass of confined gas as long as the temperature is constant. Stated as a formula, thus is: Because the before and after volumes and pressures of the fixed amount of gas, where the before and after temperatures are the same both equal the constant "k", they can be related by the equation: formula_5 In 1787, the French physicist and balloon pioneer, Jacques Charles, found that oxygen, nitrogen, hydrogen, carbon
