Dry ice is made of raw CO2. Liquid CO2 cannot exist under earth's atmosphere. For this reason, when dry ice sublimates, it turns from solid directly to gas.

Is ice dry?
yes, until it starts to melt. or its dry ice
What makes Dry Ice melt?
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.
When does dry ice melt?
Dry ice only melts when it is under pressure of 5.1 atmospheres.
What temperature does dry ice melt?
Dry ice doesn't melt. It sublimates at -78 0C, or -109 0F. Sublimation is a direct transition from a solid to a gas, skipping the liquid phase.
How fast does dry ice melt?
As a rule of thumb, dry ice sublimates at the rate of 5-10 pounds every 24 hours. Check link below for more information on dry ice and dry ice makers.
What are some good titles for science fair experiments with dry ice?
Use modeling clay to shape a volcano, then fill it with water and when you are giving your presentation, drop dry ice in it, it will begin to make fog.
If you put dry ice in 1 liter magma will it solidify or will it melt the ice?
How much dry ice? Regardless, a signifigant amount to all of the dry ice will sublime (solid CO2 will not melt under any atmospheric circumstances) and some to all of the magna will solidify into igneous rock. The results are dependent on the quantity of dry ice.
How is dry ice unique?
dry ice is actually solid carbon dioxide . it does not melt coz it directly sublimes into gaseous stat
Will dry ice melt on contact with salt?
No, dry ice will not melt on contact with salt. In the first place, dry ice does not melt. It does not have a liquid phase under normal atmospheric pressure. It transforms from solid to gas, which is called sublimation. Dry ice sublimes, rather than melts. Secondly, salt has no effect on the sublimation of dry ice. Salt has an effect on frozen water, but it does not have an effect on frozen carbon dioxide. Salt is soluble in water, it is not soluble in carbon dioxide.
Why dry ice is known as dry ice?
Solid carbon dioxide has the look and feel of ice (and is even colder). But it does not melt to a liquid, but sublimates to form a gas. So it is always dry.
Is dry ice used in skating rinks?
Yes and No at the same time because if it was real ice it would melt. But if it was dry ice we would not be able to skate on it.
Can dry ice melt in vineger?
No, but it will evaporate (or, more properly) sublimate.
