Yes, solid carbon dioxide (dry ice), like water ice, can sublimate - that is, turn directly from a solid to a gas.

∙ 12y agoThat's exactly what it does at normal atmospheric pressure. And that's exactly why
it's called "dry" ice. If you leave a lump of it on the table, it disappears, but there's
no puddle under it, because it changes directly from solid to gas and wafts away in
the breeze.
The word for this transition is "sublimation". Water ice goes from solid to liquid or
"melts", but dry ice goes from solid to gas or "sublimes".

Phase change from a solid to a gas?
A phase change from solid to gas, without going through an intermediate liquid state, is called "sublimation". For example, "dry ice" is frozen carbon dioxide. There is no liquid CO2; it "sublimates" directly from the solid to gaseous form.
How does ice turn into gas?
No, dry ice isn't a gas. It's the solid form of carbon dioxide, and it is a very good example of sublimation, which is when a solid state (dry ice) changes directly to a gas state (carbon dioxide) without first changing into a liquid state.
When substances go directly from the solid phase to the gas phase the phase change is called?
sublimation
Using the phase diagram for CO2 what phase is carbon dioxide in at -20C and 1 ATM pressure?
The triple point of Carbon Dioxide is 216.55 K (−56.60 °C) and 517 kPa (5.10 atm). Since that puts the pressure (1 atm) below the triple point pressure (5.1 atm) we are only concerned with the where the solid/vapor equilibrium line falls relative to the temperature. At 1 atm, the sublimation temperature of Carbon Dioxide is -78.5 °C - considerably below -20 °C so that puts the Carbon Dioxide firmly in the vapor region of the phase diagram.
What is the phase in which substances change directly from a solid to a gas?
i would assume that sublimation,solid to gas,would be the same answer when going from a gas to a solid.
Example of a solid bypassing the liquid phase and changing directly to the gaseous phase?
Carbon dioxide goes straight from "dry ice" to gaseous carbon dioxide.
During the process of sublimation what happens?
A solid (like dry ice- solid carbon dioxide) turns directly to a gas, without being a liquid.
What are some substances that can change directly from gas to solid states?
Iodine does not go through a liquid when changing phase. Carbon dioxide does not go through liquid phase. Both iodine and carbon dioxide sublime from a solid to a gas and condense from the gas to a solid.
When a substance changes from a solid to a gas?
The change in state from a solid directly to a gas is called sublimation. An example is frozen carbon dioxide which changes directly into gaseous carbon dioxide without going through a liquid phase.
Is dry ice subliamating into carbon dioxide a chemical change?
no. a phase change is ALWAYS a physical change in the substance.
What physical change took place when carbon dioxide is turned into dry ice?
The carbon dioxide undergoes a phase transition, from one state of matter to another, when it is turned into dry ice. This process is called deposition, and refers to a gas transforms into a solid directly.
What are some objects that sublimate?
Sublimation is the transition of a substance directly from the solid to the gas phase without passing through an intermediate liquid phase. Things that sublimate are ice, iodine, and carbon dioxide.
Dry ice converts directly to a foggy gas without melting physical or chemical change?
Dry ice is simple CO2 and at 1atm goes from a solid to a gas. Dry ice is solid Carbon dioxide and it changes physical state to gaseous Carbon dioxide without going through a liquid phase, this process of turning directly from a solid to a gas is called sublimation. As the chemical composition of the Carbon dioxide remains unchanged the change is entirely physical.
Can carbon dioxide change from a solid to a gaseous phase?
Yes, it is possible: the phenomenon is called sublimation.
Phase change from a solid to a gas?
A phase change from solid to gas, without going through an intermediate liquid state, is called "sublimation". For example, "dry ice" is frozen carbon dioxide. There is no liquid CO2; it "sublimates" directly from the solid to gaseous form.
How is carbon dioxide converted into glucose during the light independent phase?
Carbon dioxide is not energized into glucose during the Dark Phase.
Can carbon dioxude change directly from the solid phase to the gas phase?
Yes, it has no liquid phase at standard atmosphere pressure and it goes directly from solid to gas - this process is called sublimation
