Answers:
It is so cold that it does not feel wet It is frozen carbon dioxideWww@FoodAQ@Com

Dry Ice is frozen carbon dioxide, a normal part of our earth's atmosphere!. It is the gas that we exhale during breathing and the gas that plants use in photosynthesis!. It is also the same gas commonly added to water to make soda water!. Dry Ice is particularly useful for freezing, and keeping things frozen because of its very cold temperature: -109!.3°F or -78!.5°C!. Dry Ice is widely used because it is simple to freeze and easy to handle using insulated gloves!. Dry Ice changes directly from a solid to a gas -sublimation- in normal atmospheric conditions without going through a wet liquid stage!. Therefore it gets the name "dry iceWww@FoodAQ@Com

Frozen Carbon Dioxide = Dry Ice
Frozen Water = Normal Ice!.

Frozen CO2 is called dry ice because when it melts it, sublimes, it turns directly to a gas and so it doesn't pass through a liquid phase!. It is never wet, it is dry because it is either a gas or a solid!.

According to Wikipeida: http://en!.wikipedia!.org/wiki/Dry_ice
"Dry ice is solid carbon dioxide!. It is commonly used as a versatile cooling agent!. Dry ice sublimates, changing directly to a gas at atmospheric pressure!. Its sublimation and deposition point is -78!.5 °C (-109!.3 °F)!. Its enthalpy of sublimation (ΔHsub) at -78!.5 °C (-109!.3 °F) is 571 kJ/kg (245!.5 BTU/lb)!. The low temperature and direct sublimation to a gas makes dry ice a very effective coolant, since it is colder than ice and leaves no moisture as it changes state!. (Although it can carbonate food that is near)!."Www@FoodAQ@Com

Because dry ice isn't frozen water!. It's solidified carbon dioxide!. They call it dry ice because it has similar properties to ice (cold, similar texture), but obviously, it's dry - it doesn't melt, it just changes back into gas, hence the fog!.Www@FoodAQ@Com

uh dry ice is chemically different than just frozen water!.

Dry ice is the name for frozen carbon dioxide!. When it heats up it does not melt into a liquid!. It turns directly into a gas, therefore, it is a dry melting also known as dry ice!.Www@FoodAQ@Com

its liquid hydrogen!.!. cuz its not "wet"Www@FoodAQ@Com

The world may never know!.!.!.!.!.

(Likely some form of chemical reaction!.)Www@FoodAQ@Com

isnt dry ice hydrogen or helium or something like that!.Www@FoodAQ@Com

I think its liquid hydrogen!.Www@FoodAQ@Com
