If the carbon dioxide is invisible how can we see a dry ice fog?

You can see dry ice fog even though carbon dioxide is invisible due to water vapor. The visible fog is from ambient water vapor that is condensed by the extreme cold of dry ice. Without plenty of ambient water vapor, the fog output of dry ice is reduced. This is another reason why dry ice foggers often involve hot water.

What do you think the white vapor is that comes off the dry ice?
A fog of water vapour.The dry ice boils away as invisible carbon dioxide and as it does it freezes the water vapour rising off the water surface to make a mist
What is the formula for dry ice?
The dry ice is the solid form of the Carbon Dioxide (CO2) so you can name it: Carbonic anhydride, Carbonic acid gas, Carbon oxide, Carbonic oxide, Carbon(IV) oxide, and also as you called it, Dry ice (solid phase).
What is the vapor that surrounds dry ice?
80% nitrogen 20%oxegen EDIT Air is made mostly of Nitrogen (about 80% like stated before) and Oxygen (around 20%, also stated before). However, there is about one percent "Other Gases" such as Carbon Dioxide and Helium.
What is an example of gas to solid process?
An example of a solid going directly into the gas phase is frozen carbon dioxide, known as dry ice, forming a kind of "fog". This process is called sublimation, and in this case the carbon dioxide sublimes. You can observe the sublimation of frozen carbon dioxide as a kind of "fog".
What process does dry ice undergo to produce fog?
This is a sublimation process. Dry ice under atmospheric conditions does not melt, it only sublimes, so it goes directly to the gaseous phase without melting (hence the name "DRYice"). the cold CO2 gas that forms as a result, causes water molecules in the air nearby to condense and form this fog.

Why is dry ice fog bad to inhail?
Dry ice fog is mostly carbon dioxide, inhale too much and you will starve your body of oxygen, this can cause asphyxia and death within a few minutes.
What Fog is droplets of water and not carbon dioxide?
All fog (on Earth).

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.

What makes dry ice fog up?
quick answer: because pure Carbon Dioxide is heavier than the mixture of gasses we call "air" the temperature around frozen carbon dioxide (dry ice) "melts" the dry ice releasing gaseous carbon dioxide. which is still quite cold. the cold attracts water vapor which forms clouds just like you see in the sky. since pure Carbon Dioxide is heavier than the surrounding "air" it stays low and the cooled water vapor forms clouds around it until either the temperature rises above the dew point or the amount of water vapor is lowered to almost nothing (((this is the reason that bubbling caldrens (dry ice in bowl of water) slow down the cloudyness even when you add more dry ice))) if Carbon Dioxide were lighter than "air" then you would see the clouds as if they were steam rising and thus dissipating much more quickly thus the answer that CO2 is heavier than air being the reason that the fog accumulates
How would you test a gas to see if it is carbon dioxide?
Carbon dioxide gas is transparent and under normal conditions you do not see it. However, it does form visible bubbles in carbonated beverages. If you put frozen carbon dioxide ("dry ice") in water, the carbon dioxide that bubbles out of the water will look like fog, because it is very cold and causes moisture in the air to condense. But the fog will dissipate and the carbon dioxide will again become invisible.

What are characteristics of dry ice?
Dry Ice is a frozen carbon dioxide gas. The carbon dioxide is compressed and moistures is being removed.It is -109 degrees. Dry Ice cannot be touched with the human skin because of its cold substance. Dry Ice can kill our skin cells. It takes good attention. Mixing water and dry ice will cause white fog. Hope this helps. I love science and this is my research!(;
Why do you use dry ice?
Applications of dry ice (solid carbon dioxide): - cooling of foods - material for fog machines in theaters - dermatology treatments - degassing of containers from hazardous gases - blast cleaning - bombs - etc.
What happens when dry ice in water?
Dry ice doesn't chemically react with water. Dry ice is solid carbon dioxide and when heated it sublimates into (still very cold) carbon dioxide gas. The fog you see is water vapor condensing out of the air when that air is rapidly cooled by the gaseous carbon dioxide (just like when you exhale in cold weather or open the freezer in a hot and humid kitchen). The bubbling is just the carbon dioxide sublimating and the gas rising to the surface of the water.
