Dry ice is solid carbon dioxide (CO2). Humans exhale CO2 as a byproduct of the body combining oxygen breathed in and carbon from food, so breathing some CO2 is not. However, breathing only CO2 for any more than a minute or two deprives the body of oxygen, so yes, you can die from this. Also, dry ice is -109 degrees F or colder, so if you want to include thermal damage as poison, then that's another way dry ice is much more dangerous.
Dry ice is very cold, and it will damage any tissue it comes into contact with, so yes - dry ice is harmful to your lungs. However, you are probably asking about the gas generated as dry ice evaporates. That gas is Carbon Dioxide. As such, it is not harmful to your lungs, but you need to consider that you need Oxygen to survive - about 21%. (Although that gas may also be cold, so there might be an effect there as well.) If that Carbon Dioxide is displacing Oxygen, you will not be able to maintain conscienceness. Persist that beyond a short period of time, and you will die. This is an issue in rooms (Computer Centers, etc.) with Carbon Dioxide Fire Suppression. Since Carbon Dioxide is (in this case) intended to displace Oxygen, so as to put out the fire, you will certainly lose conscienceness and die if you do not leave immediately, i.e. when the pre-release alarm goes off.
Dry ice is frozen carbon dioxide, which is not a poisonous substance. You could, of course, get frostbite from it, but you could not be poisoned by it.
Dry ice is not poisonous. In fact, lots of people put it in punch at parties for a cool effect.
ice is slippery and dry ice is not because ice dosent dry out when the sun hits it and dry ice does!
a molecular solid...
Dry ice is solid carbon dioxide (CO2). It is called dry ice because it does not melt when it heats up, it goes directly from solid to gas. It is NOT the same as ordinary ice, which is of course, solid water. Dry ice is much colder than ordinary ice.
Yes, dry ice is opaque.
Dry ice is frozen carbon dioxide.
Do you sell dry ice
Simple. You keep ice in dry ice. But be careful not to eat dry ice!
Dry ice freezes and the wet ice and everything keeps cool and chilled but not frozen..obvousliy.
Dry ice is not an element. Dry ice is solid carbon dioxide, CO2, which is a compound.
Solidified Carbon Di Oxide is commonly known as dry ice. At temperature below -78.5oC, carbon di oxide converts into dry ice through sublimation.
