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 pressure, volume, and temperature of gases. In this category, we discuss different topics related to

  • Boyle’s law (discovered by Robert Boyle)
  • Charles’s law (discovered by Charles)
  • Gay-Lussac Law (discovered by Gay-Lussac)
  • Van der Waals equation (discovered by Van der Waals)

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