- Boyle’s Law
- Charles Law
- Gay-Lussac’s Law
- Avogadro’s law
- Universal Gas 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.
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 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 states that equal volumes of different perfect gases, at the same temperature (T) and pressure (P), contain equal number of molecules (n).
Combined Gas law is derived from the three gas laws Boyles law, Charles law and Gay-Lussacs law.
