How does ice turn into gas?

Answer 1

No, dry ice isn't a gas. It's the solid form of carbon dioxide, and it is a very good example of sublimation, which is when a solid state (dry ice) changes directly to a gas state (carbon dioxide) without first changing into a liquid state.

Answer 2

When ice is exposed to high temperatures above its melting point, it will change from a solid to a liquid. Once in the liquid state, further exposure to heat will cause the liquid water molecules to gain enough energy to break their bonds and escape into the air, turning into water vapor, which is the gaseous state of water.

Answer 3

Dry ice turns to gas through a process called Sublimation. This is when a solid turns directly in to a gas, bypassing the liquid state.

Dry ice is nothing more than frozen carbon dioxide. In earth's atmospheric pressure, carbon dioxide can only exist as gas and solid.

Answer 4

Sublimation is the process in which a solid turns into a gas, skipping the liquid phase.

Dry ice is a perfect example of this. Dry ice is frozen carbon dioxide. As it is exposed to room temperature, which is higher then what it needs to be to keep a stable solid form, it turns directly into a gas skipping the liquid form, since the liquid form also requires an extremely low temperature.

Answer 5

No. Dry Ice is solid Carbon Dioxide, in a supercooled state. At atmospheric pressure (aka on earth, as long as you're not in a lab, the ocean, or in an airplane), the solid carbon dioxide sublimes to the gaseous form. Sublimation is when the solid form of a compound undergoes a phase change from solid to gas without having an intermediate liquid form. Sublimation at atmospheric pressure is not a common trait of compounds, and carbon dioxide is the best example of it.

Imagine if your ice cubes turned into steam without becoming water first. Seems unlikely, right? But at the right pressure it can happen.

Refer to a phase diagram for Carbon Dioxide to see why it can sublime at atmospheric pressure (p=1atm), and how the phase transitions change at different temperatures and pressures.

Answer 6

Dry ice, i.e. solid carbon dioxide, can turn into gas directly via sublimation.

Ice from water can turn into gas by first turning into liquid water.

Answer 7

No. Dry ice goes through sublimation. That is; it goes from a solid directly to gas. Once it has enough energy to turn into a gas it will dissipate into the atmosphere.

Answer 8

Dry ice gives off carbon dioxide.
