What process does dry ice undergo to produce fog?

Answer 1

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.

Answer 2

Dry 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.

Answer 3

Dry ice undergoes sublimation when it changes from a solid directly to a gas. As the solid CO2 sublimes, it releases a dense, white fog of chilled carbon dioxide gas, which combines with moisture in the air to create the fog effect. The rapid temperature difference between the cold CO2 gas and the surrounding air causes the water vapor to condense into tiny droplets, forming the fog.

Answer 4

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

Answer 5

Sublimation: This is the process by where a solid turns directly to a gas, causing the fog like effect!
