Gas Laws

What are Gas Laws?

Gas laws in chemistry or physics identify the behavior of different gases by the general facts and common relation between the pressure, volume, and temperature of gases.

Gas laws definition, facts, formulas, and examples of gas law in chemistry and physics for ideal gases

In this category of learning chemistry, we discuss different topics related to formula and derivation of gas law.

  • Boyle’s law: Discovered by physicist Robert Boyle in 1662 and provides the relation between pressure and volume of gas at constant temperature.
  • Charles’s law: Discovered in 1787 by Jacques Charles but quantitative experiments establishing the law were first published in 1802 by Joseph-Louis Gay-Lussac.
  • Avogadro’s Law: Discovered in 1811 by the Italian chemist Amadeo Avogadro.
  • Gay-Lussac Law: Discovered by Joseph-Louis Gay-Lussac in 1808 and published in 1809.
  • Graham’s law of diffusion: Discovered by Thomas Graham in 1848)
  • Dalton’s law of partial pressure: Observed by John Dalton in 1801 and published in 1802)
  • Van der Waals equation: Discovered by Van der Waals in 1873)

The above gas laws or formulas are used in chemistry or physics to derive the properties of ideal and real gases.
