Robert Boyle Robert Boyle. The following are some of the more important of his works: Among his religious and philosophical writings were: 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
Combined gas law pressure as long as it is at a constant volume. The inter-dependence of these variables is shown in the combined gas law, which clearly states that: This can be stated mathematically as: where: For comparing the same substance under two different sets of conditions, the law can be written as: The addition of Avogadro's law to the combined gas law yields the ideal gas law. Boyle's Law states that the pressure-volume product is constant: Charles's Law shows that the volume is proportional to the absolute temperature: Gay-Lussac's Law says that the pressure is proportional to the absolute temperature: The algebraic
