How does dry ice work when it's put in water?

Answer 1

When dry ice is put into water it sublimes.

CO2(s) --> CO2(g)

Answer 2

the water does not boil, but the dry ice starts giving off CO2 gas very quiclky, which bubbles up and looks like the water is boiling. dry ice goes from solid straight to gas at temperatures well below 0.

Answer 3

When ice is put in water, it slowly cools the temperature of the water around it. It's a sort of diffusion technique. Oh wait, you said DRY ice....... well it's almost the same thing except the vapors it gives off. If you put it in hot water you get more vapor.

Answer 4

Dry Ice is frozen carbon dioxide, a normal part of our earth's atmosphere. It is the gas that we exhale during breathing and the gas that plants use in photosynthesis. It is also the same gas added to water to make soda water. Dry Ice is particularly useful for freezing, and keeping things frozen because of its very cold temperature: -109.3°F or -78.5°C. Dry Ice is widely used because it is simple to freeze and easy to handle using insulated gloves. Dry Ice changes directly from a solid to a gas -sublimating - in normal atmospheric conditions without going through a wet liquid stage.
