What else can I help you with?
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.
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 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.
Is fog an element?
no, fog is tiny droplets of water, a compound.
Fog and a mixture a fine water droplets in the air example of an emulsion yes or no?
No, fog and a mixture of fine water droplets in the air are not examples of an emulsion. An emulsion is a mixture of two or more immiscible liquids where one is dispersed in the other, such as oil and water in mayonnaise. Fog is a suspension of water droplets in the air.
Do clouds give off oxygen or carbon dioxide?
No, not at all ! Clouds are just water that has come out of the air when they hit chillier air. Sometimes clouds go clear to ground, and are called, "Fog". Water in the atmosphere is an important greenhouse gas that helps protect us from being frozen solid at night or fried by the Sun during the day. The planet Mercury is like this because it has no water vapor in its nearly non-existant atmosphere. For the most part, plants take in carbon dioxide and give off oxygen. And animals take in oxygen and give off carbon dioxide. Handy, isn't it?
How many droplets of water in a seven block fog and would this fill a glass half full?
It depends on the size of each water droplet and the density of the fog. It is unlikely that the water droplets in a seven block fog would be enough to fill a half-full glass, as fog droplets are typically very small.
What do you call water vapor that has condense into small water droplets near the ground?
A collection of water droplets suspended in the air is called a cloud. If the collection of water droplets is close to the ground it is called fog.
How many droplets of water that make up fog would it take to make a single tablespoon of water?
It would take about 450 million droplets of fog to make a single tablespoon of water. Fog droplets are typically very small, around 10-15 micrometers in diameter.
What do you call droplets of water in the air?
Droplets of water in the air are called mist or fog, depending on their size and density. Mist generally consists of fine droplets, while fog is denser and reduces visibility.
How is fog made?
Fog shows up when water vapor, or water in its gaseous form, condenses. During condensation, molecules of water vapor combine to make tiny liquid water droplets that hang in the air. You can see fog because of these tiny water droplets.
What is the state of water in fog?
Fog is composed of tiny water droplets suspended in the air, which are in liquid form. This liquid water vapor condenses into small droplets when the air is cooled to its dew point.
