Most machine guns are belt-fed weapons that fire from 500 to 1, 000 rounds per minute and will continue to fire as long as the trigger is held back or until the supply of ammunition is exhausted.

Detailed explanation-2: -Gunpowder burns rapidly when it ignites, producing a lot of hot gas in the process. The hot gas applies much greater pressure on the powder side of the¬ cannonball than the air in the atmosphere applies on the other side. This propels the cannonball out of the gun at high speed.
