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
Potential temperature Potential temperature The potential temperature of a parcel of fluid at pressure formula_1 is the temperature that the parcel would attain if adiabatically brought to a standard reference pressure formula_2, usually 1000 millibars. The potential temperature is denoted formula_3 and, for a gas well-approximated as ideal, is given by where formula_5 is the current absolute temperature (in K) of the parcel, formula_6 is the gas constant of air, and formula_7 is the specific heat capacity at a constant pressure. formula_8 for air (meteorology). The concept of potential temperature applies to any stratified fluid. It is most frequently used in the
