Question

Why is carbon dioxide stored under high pressure in fire extinguisher cylinders?

Answer 1

Answer:

here is answer

Explanation:

Carbon dioxide (CO2) extinguishers contain a mixture of liquid and gaseous carbon dioxide (a nonflammable gas). CO2 is normally a gas at room temperature and pressure. It has to be stored under high pressure to make it a liquid. When you release the pressure, the gas expands enormously and makes a huge white jet.
