Boyle's law (sometimes referre to as the Boyle-Mariotte law) is one of the gas laws and basis of derivation for the ideal gas law, which describes the relationship between the product pressure and volume within a closed system as constant when temperature and moles remain at a fixed measure; both entities remain inversely proportional. The law was named after chemist and physicist, Robert Boyle who published the original law in 1662. The law itself can be defined succinctly as follows:
