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
Thermodynamic instruments volume, area, mass, and force. These may be combined to understand the concept of pressure, which is force per unit area and density, which is mass per unit volume. It has been experimentally determined that, at low enough pressures and densities, all gases behave as ideal gases. The behavior of an ideal gas is given by the ideal gas law: where "P" is pressure, "V" is volume, "N" is the number of particles (total mass divided by mass per particle), "k" is Boltzmann's constant, and "T" is temperature. In fact, this equation is more than a phenomenological equation, it gives
