Avogadro's law
Avogadro's Law (pronounced: av-uh-gah-drohz law) is a fundamental principle in the field of Chemistry and Physics. It is named after the Italian scientist Amedeo Avogadro, who proposed the law in 1811.
Etymology
The term "Avogadro's Law" is derived from the name of its proposer, Amedeo Avogadro. The word "law" in this context refers to a scientific principle that is generally accepted to be universally true.
Definition
Avogadro's Law states that equal volumes of all gases, at the same temperature and pressure, have the same number of molecules. This is often expressed mathematically as V/n = k, where V is the volume of the gas, n is the number of moles of the gas, and k is a constant.

- Mole (unit): The mole is the unit of measurement in the International System of Units (SI) for amount of substance. It is defined as exactly 6.02214076×10²³ particles, which may be atoms, molecules, ions, or electrons.
- Ideal Gas Law: The ideal gas law is the equation of state of a hypothetical ideal gas. It is a good approximation of the behavior of many gases under many conditions, although it has several limitations.
- Gas Constant: The gas constant is the constant in the ideal gas law with symbol R. It is equivalent to the Boltzmann constant, but expressed in units of energy per temperature increment per mole.
