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.

∙ 15y agoDry ice is very cold, solid carbon dioxide. When placed in water it lets off bubbles of very cold carbon dioxide gas. As this cold gas mixes with the surrounding air, the drop in temperature causes tiny droplets of liquid water to form in that air, which is visible as a fog (just as your water-laden breathe condenses to fog outside on a cold day). The fog caused by cold carbon dioxide gas is a mixture of tiny droplets of liquid water, cold carbon dioxide gas and air that has been cooled by the cold carbon dioxide gas, so it falls down through warmer air and stays close to the table or floor because carbon dioxide is heavier than air, and cold air is heavier (denser) than warm air. The "fog" will remain visible until the gasses the water droplets are suspended in warms up again, e.g. by being stirred up and mixed with warmer air.

∙ 12y agothe cold temperature of dry ice and the warm temperature of the water makes it melt quickly causeing the dry ice to turn into co2

Does dry ice produce more fog with running water than with still water?
Still water. If you have running water it takes more time to settle.
What is an hypothesis for dry ice?
Hypothesis: I think the fog will affect the bubble and the expect that when all the fog builds up into the bubble the dry ice bubble is going to burst. I think that because when all the fog from the dry ice builds up in to the bubble then it is going to burst.
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.
If you let dry ice evaporate?
it will make fog
What produces the fog on stage and in films?
Dry ice
What processes does dry ice undergo in order to create the fog?
sublimation
Does dry ice produce more fog if the temperature of the water is cold?
Dry ice is formed from CO2, water has nothing to do with it.
How tall will hot ice stand after it is made?
Dry Ice when combined with hot tap water can produce vigorous bubbling water and voluminous flowing fog. For example, with 5 pounds of Dry Ice in 4 to 5 gallons of hot water, the greatest amount of fog will be produced the first 5 to 10 minutes. There will be far less fog for the next 5 to 10 minutes as the water cools down and the volume of Dry Ice diminishes. As the water cools, the fog becomes wispier. Dry Ice makes fog because of its cold temperature, -109.3°F or -78.5°C, immersed in hot water, creates a cloud of true water vapor fog. When the water gets colder than 50°F, the Dry Ice stops making fog, but continues to sublimate and bubble. The fog will last longer on a damp day than on a dry day.
What is dry ice for?
dry ice is for mixing with water to make fog
Does dry ice produce more fog with running water than with still water?
Still water. If you have running water it takes more time to settle.
What is the process that changes cloud into fog?
Fog is a cloud on the ground.
What is the fog you see in the air around the dry ice in figure 13 Why does the fog form?
because the figure is the smallest than the fog
What is an hypothesis for dry ice?
