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
The vapour is water vapor condensing out of the air. Carbon dioxide gas is colorless.
sublimation The vapor from the dry ice will extinguish the flame from the candle.
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.
it turns into oxygen
Air can be dry at any temperature. It all has to do with the actual amount of water vapor in the air.
Wet volume includes the vapor pressure of water, while dry volume does not.
sublimation The vapor from the dry ice will extinguish the flame from the candle.
Dry water vapor.
The vapor created is not from the dry ice itself, nor is it from the water bucket you're probably putting it in. The vapor comes from water vapor in the air that is condensing because of the cool air. It's like what happens when you breathe on a cool mirror.
Water vapor
the difference between dry air and atmospheric air is that atmospheric air contains water vapor but dry air contains no water vapor
Dry what? Perhaps the water is evaporated, and becomes vapor in the air.
It is. Dry air lacks water vapor, not oxygen.
It doesn't! The dry ice boils, while the water gets cold. It just LOOKS like the water is boiling. If you capture and analyze some of the gas that comes off, you will see that it's carbon dioxide (dry ice), not water vapor.
A dry steam cleaner works by turning water into dry steam vapor. The cleaner heats water under high pressure which turns the water into a vapor that has very little moisture.
Yes.
