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
They are both solids and are hard. Also, they are odorless and cold, and usually have white tints. When they are kept out long enough, they will melt/ sublime and change from a solid to a liquid or gas.
Certainly you can; in fact, if you're not going to use it immediately, doing so is probably a good idea.Things that would be a bad idea:Putting it in a sealed, airtight ice chest.Keeping it in an unsealed, non-airtight ice chest with you (or anyone else) in a sealed, reasonably airtight enclosure, or even an open one if the openings to the outside air are above head height.Mixing it up with your regular ice chest and putting chunks of dry ice in your soft drinks. (Actually, this could be a great idea, but you want to be sure you don't tilt the glass so far the dry ice touches your lips.)Messing around with dry ice in general without insulated gloves ... due to the Leidenfrost effect you may be able to get away with this if you're careful, but use the gloves anyway.
I have been looking for this info as well. So far I have found that for domestic wells approximately 60 to 80# of dry ice is used while for larger commercial wells up to 800# may be used. If the well has a large amount of casing say over 150 feet one should be able to add the dry ice and quickly cap the well. If there is a lesser amount of casing one risks having the resulting pressure blow out or unseat the casing and losing the seal. In this case one must make some other arrangement to seal off the well below the casing in order to contain the prssure without damage to the seal.
In general, it depends. Most of the time, it is translucent because you can only see unclear images through the fog. Other times, if you can't see anything through the fog, then it is opaque, not translucent.
crush it
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.
Carbon dioxide .
Yes it does. Everything in the universe is made up of elements. Elements are a combination of atoms.
No, dry ice is frozen carbon dioxide, or CO2.
Dry ice sublimes when it is exposed to air. This means it changes directly from a solid to a gas without going through the liquid phase. As dry ice warms up, it releases carbon dioxide gas, creating the characteristic fog or smoke effect.
I'm not for sure but i believe that the dry ice smoke first moves upward because the force of the sublimination creates thermal energy and causes the fog to heat up slightly so the dry ice fog is lighter and slightly warmed then surrounding air thanks to the cooling of dry ice. After a while it might move downward because as the gases start to cool down they become heavy and the carbon dioxide (since its denser) floats to the ground. I have no idea whether this is correct.... just a slightly educated guess.
i would say yes because the fog will keep adding up until it pours out of the container it's being held in.
Dry Ice is made up of a chemical. When exposed to air it dissipates. The more the air gets to it the faster it disappears. To make you dry ice last longer, just keep your container closed and make sure it is air tight. The Ice Cream Man
the vapors of the dry ice fill up the ballon with gas
Make fog in a bottle with hot waterIn this case the condensation is caused by the temperature variation between simple ice and hot water. 1. Fill up the jar or bottle completely with very hot water and let it stay there for about 60 seconds. 2. Pour out all but about an inch of the hot water. 3. Put a strainer or bag over the top of the jar. 4. Place ice cubes in the strainer or plastic bag. 5. Fog will form as the hot water vapor from the bottom of the bottle contacts the cold air created by the ice cubes and begins condensation.and there ya go. hehe
When air becomes laden with moisture, the moisture condenses and becomes saturated. This cooler area of air begins to form fog at ground level or just above the ocean / water surface. If this is over ice flow or icebergs, the air also contains ice crystals in the fog. Like on land, the ice fog occurs evening to next morning. As the sun comes up, it warms the air, melts ice crystals, reduces the condensation, and like on land, the entire fog cloud or fog bank becomes lighter. The fog rises into the sky, becoming just one of the clouds.
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.
