Answer: A-A gravity air displacement sterilizer works when pressurized steam pushes air out of the sterilizing chamber, and high-pressure steam sterilizes the instruments. This is the action of one type of autoclave, used for steam sterilizing instruments and supplies. The instruments are placed within the enclosed chamber while the outer jacket controls the amount of steam emitted into the chamber. This steam displaces the air, and is then able to sterilize the instruments.
