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
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
