Question

why carbon dioxide forms gas in low pressure and why it's from solid in high pressure?

Detail Explanation​

Answer 1

Answer:

When a liquid is cooled to even lower temperatures, it becomes a solid. The volume never reaches zero because of the finite volume of the molecules. ... Carbon dioxide, for example, is a gas at room temperature and atmospheric pressure, but becomes a liquid under sufficiently high pressure.

Answer 2

Answer:

Because the moleculs link together and it form solid and when the moleculs are loose then they will form gas
