When a flat tyre is filled with with air, the increased volume of air in the flat tyre results in the flat tyre recovering its previous shape. The volume of air pumped into the tyre will be directly number of molecules of air that are held within the tyre’s capacity. Which gas law best explains the process involved?

Avogadro’s Law

Boyle’s law

Guy Lussac Law

Charle’s Law

Charle's Law

The gas law that best explains the process involved is Boyle's Law. Boyle's Law states that at constant temperature, the volume of a gas is inversely proportional to its pressure. In the case of filling a flat tire with air, as the volume of air inside the tire increases, the pressure inside the tire also increases. This increase in pressure helps the tire recover its previous shape.
