Combined Gas Law

Definition - What does Combined Gas Law mean?

Combined Gas Law is a gas law which is a combination of the Boyle's Law, Gay-Lussac's Law and Charles's Law. The law is considered as a consequence of these three laws. Interrelation of these variables can be seen in Combined Gas Law that states that ratio between pressure-volume product and temperature of systems remains constant. Using this gas law helps to mathematically predict the consequences of change in temperature, volume and pressure. The law can also be used in explaining mechanics where temperature, volume and pressure are affected.

Petropedia explains Combined Gas Law

Combined Gas Law uses the relationships share by temperature, pressure and volume which are the variables found in Boyle's Law, Gay-Lussac's Law and Charles's Law. This is considered as an amalgamation of these three previously occurring laws as no official founder is known for this law. Boyle's law states that volume and pressure, at a fixed temperature, are inversely proportional to each other. Gay-Lussac's law affirms the proportionality between pressure and temperature till it is at constant volume. Finally, the Charles's law states that temperature and volume are directly proportional to each other until the pressure is kept constant.
