Solution
- Firing a bullet: When gunpowder burns, it creates; a significant amount of superheated gas. The high pressure of the hot gas behind the bullet forces it out, of the barrel of the gun.
- Heating food in an oven: When you keep food in an oven for heating, the air inside the oven is heated, thus pressurized.
