# The Ideal Gas Law Equation

The ideal gas law is PV = nRT. Putting n and T as constant in the ideal gas equation, we have PV = constant. This is Boyle's law. When P and n are constant, we get Charles's law i.e., V = T × constant. Gay-Lussac's law is obtained when V and n are constant. The equation is P = T ×constant.

1. In thermodynamics, Ideal gas law is a well-defined approximation of the behavior of many gases under diverse conditions. Ideal Gas Equation is the combination of empirical laws like Charle’s law, Boyle’s law, Gay-Lussac’s law, and Avogadro’s law. Ideal Gas Equation is the equation defining the states of the hypothetical gases expressed mathematically by the combinations of empirical and physical constants. It is also called the general gas equation. It can be defined as:

Ideal Gas Equations: Ideal Gas Behaviour, Value of R, Videos, Examples

1. The ideal gas law, also known as the general gas equation is an equation of state of a hypothetical ideal gas. Although the ideal gas law has several limitations, it is a good approximation of the behaviour of many gases under many conditions. The ideal gas law was stated by Benoit Paul Émile Clapeyron in 1834 as a combination of the empirical Charles’s law, Boyle’s Law, Avogadro’s law, and Gay-Lussac’s law. The empirical form of ideal gas law is given by:
