It is called dry ice because it goes directly between a solid and gas state at-78 degrees Celsius, skipping the liquid phase.
Water ice becomes water when it melts. Frozen carbon dioxide sublimates; it goes from being solid to gas without going through a liquid stage. as it doesn't give a moist touch it is known as dry ice.
The frozen carbon dioxide will eventually evaporate (melt) yet will leave a dry patch. Frozen water (ice) will leave a pool of water once it has melted.
Dry ice sublimates meaning it goes directly from solid to gas without going through the liquid state. This means that there is never any liquid unlike regular water ice making essentially dry, thus the name dry ice.

Dry ice is the solid form of carbon dioxide, instead of water. The reason why it's called dry ice is under normal circumstances, heating dry ice will turn it directly into a gas, skipping a liquid form. The exception in all cases is under high pressure will melting dry ice turn into a liquid.
Because it does not melt - it dissipates, at which time it turns into a carbon dioxide gas, and not a liquid.
It is called dry ice because it goes directly between a solid and gas state at-78 degrees Celsius, skipping the liquid phase.
It is called dry ice because it looks like ice, but when it melts, no water comes out. It is dry. It looks like ice. This is why it is called that
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.
Sublimation is the conversion of dry ice.
Dry ice doesn't melt, it changes from a solid state, to a gas state, that's why it's called DRY ICE, there is no known way that it melts.

Dry ice is the solid form of carbon dioxide.
Sublimation is the conversion of dry ice.
Solid Carbon Dioxide is called dry ice because on sublimation, it directly changes to gas. It does not have an intermediate liquid state. Thus, when it is frozen, it does not melt. Therefore, as it does not change into liquid and is dry, it is called Dry ice.
There is no ice escaping. Rather the dry ice is becoming a gas. It's called sublimation.
It is called dry ice because it looks like ice, but when it melts, no water comes out. It is dry. It looks like ice. AND IF YOU EAT IT YOU CAN DIE. you can't eat it
It is called "dry" because when heat is given, it sublimes (turns from a solid into a gas). This is different from actual ice that turns from a solid to a liquid. It is called "ice" because solid carbon dioxide (dry ice) is very cold, similar to ice.
When ice transforms to water, it is called melting. If it is dry ice, and it evaporates, that is called sublimation.
that is dry ice!!!
