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 laws pressure, volume, and temperature for a fixed mass (quantity) of gas: This can also be written as: With the addition of Avogadro's law, the combined gas law develops into the ideal gas law: These equations are exact only for an ideal gas, which neglects various intermolecular effects (see real gas). However, the ideal gas law is a good approximation for most gases under moderate pressure and temperature. This law has the following important consequences: or Gas laws The gas laws were developed at the end of the 18th century, when scientists began to realize that relationships between pressure, volume and
