🇬🇧 Airlock meaning: English Vocabulary Flash Card

An airlock is a special small room used when two places have different kinds of air or air pressure. You go into the airlock, close the door behind you, and then the air in the room is carefully changed so it matches the air on the other side. After that, you can safely open the next door and go through. Airlocks are often used on spaceships, submarines, and some science labs so the air doesn’t rush in or out and people stay safe.
