Question

Why is solid carbon stored known as dry ice. Why is it stored under high pressure?

Answer 1

Answer:

Because it looks like ice and when it “melts” (it actually sublimes) it goes from solid straight to gas, no liquid, hence dry ice.

Solid carbon dioxide is stored under high pressure. This is because on decreasing the pressure on solid carbon dioxide , it gets converted directly into carbon dioxide gas.

Explanation:

Answer 2

Answer:

solid carbon dioxide directly changes into carbon dioxide gas without passing through the intervening liquid state . it is extremely cold substance and does not wet the surface . hence it is called dry ice . it is stored under high pressure because the pressure on decreasing the pressure solid carbon dioxide converts to gas.
