Dry ice can be melted into liquid form at pressure over 5.11 times atmospheric pressure. Reference the Phase Diagram of Carbon Dioxide at
http://www.science.uwaterloo.ca/~cchieh/cact/c123/phasesdgm.html
(If that page is no longer available, search for the keywords "phase diagram" & "carbon dioxide")
In that diagram, X is the triple-point. This is the pressure (5.11 atm) and temperature (-56.4C) at which the solid, liquid and gaseous phases for CO2 co-exist. At below that pressure (as Y with 1 atm,) CO2 changes from solid to gas as temperature increases. At above that pressure (as Z with 73 atm,) solid CO2 melts into liquid before changing to gas as temperature increases.

Can dry ice be refrozen before it starts to melt?
it it can the part that hasent started melting
What is the common name of solid CO2 why it is called so?
Dry Ice, a white (powdery) solid, even colder than ice but no water is left when melting or subleming.
Does cyclohexane freeze in dry ice?
Cyclohexane's melting point is about +6 degrees Celsius. Dry ice (solid carbon dioxide) maintains a temperature of -78C in normal conditions. Cyclohexane will thus freeze on dry ice. In fact, a closed container of cyclohexane would freeze on regular, water ice. Regular hexane (linear) has a freezing point around -100C, and will remain a liquid on dry ice, much as ethanol or acetone do.
Is boiling point higher than melting point?
they are the same... dont know who wrote this but it can be the same such as dry ice, or different such as water. however boiling point will sometimes be higher than melting point
What are characteristics of dry ice?
Dry Ice is a frozen carbon dioxide gas. The carbon dioxide is compressed and moistures is being removed.It is -109 degrees. Dry Ice cannot be touched with the human skin because of its cold substance. Dry Ice can kill our skin cells. It takes good attention. Mixing water and dry ice will cause white fog. Hope this helps. I love science and this is my research!(;
How do you prevent ice from melting?
Simple. You keep ice in dry ice. But be careful not to eat dry ice!
What keeps a snowball from melting?
dry ice
What is the difference between ice point and melting point?
ice point = cannot freeze anymore melting point = cannot melt any more
Name of the ice to water?
When ice transforms to water, it is called melting. If it is dry ice, and it evaporates, that is called sublimation.
How does dry ice in a ice cream cart disappear?
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
How hot can ice-cream get with out melting?
Ice cream cannot get "hot" at all before melting. It will begin to melt as soon as it is removed from refrigeration.
Will melting dry ice make a water puddle?
Unless the dry ice is under pressure, it will "sublime" and change from a solid to a gas. Therefore, there will be no "puddle".
What happens when dry ice melts?
Rather than melts, dry ice evaporates. This process is called sublimation and happens at a slower rate than the melting of water ice.
When the ice melt?
Dry ice is carbon dioxide in solid form. CO2's melting point is -78oC
Can you reuse dry ice?
If you mean the dry ice bomb as in putting dry ice in a bottle and sealing it, and then having it explode, then no. The bottle and the dry ice cannot be reused from the Dry Ice Bomb. The reasoning is that the Dry Ice would have already used enough of its fuel to try to explode the bottle that no fuel is left to explode another, and the bottle would be ripped in half by the Dry Ice inside, so the bottle cannot be reused.
Can dry ice be refrozen before it starts to melt?
it it can the part that hasent started melting
Why do ice cubes explode in drink?
Ice cubes explode in a drink because they are melting at a fast rate. The ice cannot contract fast enough to keep up with the melting, which causes it to crack.
