Oxygen cylinders contain oxygen in _______ state.

Open in App

Solution

(1) Air contains mostly nitrogen and oxygen gases.
(2) Gases change to a liquid state when the temperature is decreased and pressure is increased.
(3) Oxygen cylinders used in the hospitals for patients contain oxygen in liquid form.
Therefore, oxygen cylinders contain oxygen in a liquid state.
