They are compressed so that a larger amount of gas can be stored in a smaller container. A greater mass confined to a smaller volume makes transporting and storing of gases easier. Increasing temperature increases pressure, and the cylinders might explode. Before compressed oxygen can be breathed, it must be decompressed.
Answer: Large Amount of gas can be stored in the small container
Explanation: Gases such as oxygen found in tanks used as hospitals are compressed because on compressing the gas, its volume decreases which will help to store large amount of gas.
This large amount can be stored in the small container.
Care must be taken as temperature should be not increased because as temperature will increase, pressure will also increase and this could lead to the explosion of the cylinder . Thus preventive measures must be taken.
