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 collecting tube evacuated tube and the liquid-containing tube gives the mass (formula_7) of the sucked-in liquid, that took the place of the extracted amount of gas.) The given mass-density formula_8 of the liquid permits to calculate the displaced volume (formula_9). Thus giving mass formula_10 and volume formula_11 of the extracted amount of gas, consequently accessing its mass density (formula_12) under atmospheric pressure The mass density of a fluid can be measured by using a gas collecting tube, an analytical balance and two other fluids of known mass densities, preferably a gas and a liquid (with mass densities formula_13, formula_8).
