WebNov 16, 2024 · Dry ice is solid. It sublimates or changes states from a solid to a gas at temperatures of -78 degrees Celsius under normal atmospheric pressure of 1 atm. When … WebDry ice (CO 2) works the same way. It sublimes, because the pressure at the surface of the Earth is too low for liquid CO 2. If you could take the dry ice to a place where the pressure is much higher (like the bottom of the ocean, or a special laboratory) you could actually watch it melt, then boil, just like H 2 O at the surface of the Earth.
