Gay-Lussac's law

Joseph Gay-Lussac

He is the guy how found that the pressure of a gas varies directly with the temperature of the gas. So we also call it Gay-Lussac's law.

The law of combining volumes states that, when gases react together to form other gases, and all volumes are measured at the same temperature and pressure:The ratio between the volumes of the reactant gases and the products can be expressed in simple whole numbers.

We get the formula as: P1/T1=K

Real life Examples:

A real life example of Gay-Lussac's law is the firing of guns or canons. When gun powder burns it creates a large amount of super hot gas. The pressure from the gas pushes the bullet out of the barrel.
