Dry ice is I believe carbon in solid form. At room temperature it immediately turns from solid to gas bypassing the liquid stage of matter. It is simply to warm for it to keep its solid form at room temperature. Its solid temperature is close to -200 degrees fahrenheit.

∙ 13y agoThe dry ice is undergoing the process of sublimation, wherein a solid changes directly into a gas, skipping the fluid state, because the temperature of the water is significantly higher than the temperature in which CO2 can exist as a liquid in atmospheric pressure.

∙ 10y agoDry ice is frozen carbon dioxide which is clear just like air. The "smoke" is water. The cold temperatures cause water in the gas phase (which is invisible) to condense into tiny water droplets which are visible because they refract light. In air you get very little "smoke" but it is visible. If you drop some dry ice in water you get much more of this smoke. The dry ice melts and boils directly from solid to gas and this gas motion helps push the water droplets upward.

∙ 13y agoIt's not "smoke", it's fog. Just like regular fog, it's tiny droplets of water suspended in the air.

∙ 13y agoLol, been long time since I heard of dry ice me and my dad used to put some in a bottle mixed with other stuff and it would blow up lol... anyway: last time I saw I think it did yes :).

Why does dry ice make more smoke in hot water than in cold?
The idea is simple - drop a chunk of dry ice in some water; it will bubble and smoke. In practice, this is a little more difficult, because the dry ice will cool down the surrounding water and start to form a shell around itself of water-ice. Eventually the smoking and bubbling stops. The only way to keep this from happening is to keep the water hot, which increases the rate at which the dry ice is consumed. That's why dry ice isn't really used as often as people think it is.
what is called when dry ice changing into smoke?
"sublimation"
Where is sublimation seen?
Sublimation can be seen when dry ice, or solid carbon dioxide, turns into smoke.
Why did the dry ice smoke falls to the floor and flow downwards?
Dry ice, carbon dioxide, is more dense than air.
How does the temperature of water affect the sublimation of dry ice?
cold water makes dry ice closer to its freezing point. so hot water makes dry ice sublimate more
How can instantaneous smoke be produced by a reaction?
dry ice and water enjoy

Why the dry ice first time the smoke will move up aftera few mins the smoke move downwards?
because of the carbon dioxide in the dry ice because of the carbon dioxide in the dry ice because of the carbon dioxide in the dry ice
When dry ice gives off smoke what is the compound formed?
When dry ice appears to give off smoke it is solid carbon dioxide subliming to vapor. The "smoke" is thus carbon dioxide gas. Dry ice is also often used in the theatre/television/movies etc. because it is cold enough to condense water vapour in the air to produce fog that may resemble smoke. Please see the link.
Is dry ice changing into theatrical smoke physical or chemical change?
Dry ice doesn't "turn into smoke". Dry ice causes moisture in the air to condense, forming fog. This is a purely physical, not chemical, change.
How do you make smoke without a smoke machine and dry ice?
start a fire
what is called when dry ice changing into smoke?
"sublimation"
Where is sublimation seen?
Sublimation can be seen when dry ice, or solid carbon dioxide, turns into smoke.
What is causing the change in dry ice and the water ice?
Temperature causes changes in dry and water ice
Why did the dry ice smoke falls to the floor and flow downwards?
Dry ice, carbon dioxide, is more dense than air.
What is dry ice for?
dry ice is for mixing with water to make fog
Is that water vapour or carbon dioxide form the smoke during dry ice sublimation?
The visible "smoke" is water vapor condensing from the surrounding air into tiny water droplets (basically, fog). Gaseous carbon dioxide is clear and colorless.
