Gas Laws explain the behavior of an ideal gas in terms of temperature, pressure, volume.

The following are the some of the important gas laws:

- Boyle’s Law
- Charles Law
- Gay-Lussac’s Law
- Avogadro’s law
- Universal Gas Law

## Boyle’s Law:

Boyle’s law states that the volume of a given mass of gas *(V)* is inversely proportional to its absolute pressure *(P)*, provided the temperature of the gas* (T)* remains constant.

## Charles Law:

According to Charles law, the volume of a given mass of gas (V) is directly proportional to its absolute temperature (T), when its pressure remains constant.

## Gay-Lussac’s Law:

Gay-Lussac’s Law is also know as *Amontons’ law*. It states that if the volume of a given mass of a gas *(V)* is kept constant, then the pressure of the gas *(P)* is directly proportional to its absolute temperature *(T)*.

## Avogadro’s Law:

Avogadro’s law states that equal volumes of different perfect gases, at the same temperature *(T)* and pressure *(P)*, contain equal number of molecules *(n)*.

## Universal Gas Law:

Combined Gas law is derived from the three gas laws Boyles law, Charles law and Gay-Lussacs law.
