Boyle's law of the gas, and "k" is a constant. The equation states that the product of pressure and volume is a constant for a given mass of confined gas and this holds as long as the temperature is constant. For comparing the same substance under two different sets of conditions, the law can be usefully expressed as The equation shows that, as volume increases, the pressure of the gas decreases in proportion. Similarly, as volume decreases, the pressure of the gas increases. The law was named after chemist and physicist Robert Boyle, who published the original law in 1662. This relationship
Gas the volume is doubled, the pressure is halved. Given the inverse relationship between pressure and volume, the product of pressure ("P") and volume ("V") is a constant ("k") for a given mass of confined gas as long as the temperature is constant. Stated as a formula, thus is: Because the before and after volumes and pressures of the fixed amount of gas, where the before and after temperatures are the same both equal the constant "k", they can be related by the equation: formula_5 In 1787, the French physicist and balloon pioneer, Jacques Charles, found that oxygen, nitrogen, hydrogen, carbon
