sublimation doesnt nessicarily have anything to do w/ temperature. it is observed in substances such as CO2 (Carbon Dioxide) which have high vapor pressure and low intermolecular force. i take no responsibility for any harm done to u or whoever tests this in some krazy way reading my response to this question....

∙ 15y agoSublimation is an endothermic process. A substance must gain or absorb a high amount of energy in order to change directly from a solid to a gas, skipping the liquid phase completely. Sublimation must happen below the triple point of a given substance. The triple point is the temperature and pressure at which a substance can exist as a solid, liquid, and gas in equilibrium.

∙ 11y agoSublimation is not exothermic.
Sublimation, where a solid turns directly into a gas, is endothermic. Energy (heat) must be added to the substance to bring on the phase change.
The opposite, deposition, where a gas turns directly into a solid, is exothermic.

Dry ice is an example of which process?
Dry ice is solid carbon dioxide. The conversion from solid to gas which carbon dioxide undergoes is called sublimination. the process where dry ice is changed into carbon dioxide is called sublimation.
What are the starting and ended phases for sublimation?
Sublimation is the transition from solid directly to gas without passing through a liquid phase (e.g. dry ice is solid carbon dioxide at very low temperatures which sublimes into carbon dioxide gas).
What happen when oxygen combines with a hydrocarbon to form water and carbon dioxide?
It reacts with oxygen to produce carbon dioxide, water, and heat.
Is the combustion of propane endothermic or exothernic?
In the presence of excess oxygen, propane burns to form water and carbon dioxide. When not enough oxygen is present for complete combustion, incomplete combustion occurs when propane burns and forms water, carbon monoxide, and carbon dioxide.
What is the sublimation of carbon dioxide a chemical property or chemical change?
It is a change in physical state, which is a physical change.
Dry ice is an example of which process?
Dry ice is solid carbon dioxide. The conversion from solid to gas which carbon dioxide undergoes is called sublimination. the process where dry ice is changed into carbon dioxide is called sublimation.
Is carbon dioxide formation endothermic and exothermic?
Exothermic because the heat of formation is -566. Exo- is negative and Endo- is positive.
Is dry ice exothermic?
Dry ice is the cold dense white mist produced by solid carbon dioxide in the air. The sublimation of dry ice is an endothermic reaction.
What is dry ice and how is it connected to sublimation?
Dry ice is solid carbon dioxide. Carbon dioxide goes from a solid phase to a gaseous phase without becoming a liquid and that transition is called sublimation.
When a chunk of dry ice is at room temperature a cloud of carbon dioxide vapor forms The carbon dioxide is changing from?
The solid carbon dioxide is transformed directly in gaseous carbon dioxide; this phenomenon is called sublimation.
When a chunk of dry ice is at room temperature a cloud of carbon dioxide vapor forms. The carbon dioxide is changing from a?
The solid carbon dioxide is transformed directly in gaseous carbon dioxide; this phenomenon is called sublimation.
Where is sublimation seen?
Sublimation can be seen when dry ice, or solid carbon dioxide, turns into smoke.
What does frozen carbon dioxide undergo?
if it is taken out of the deep freeze it will undergo sublimation.
What is the name of the process due to which ice changes into carbon dioxide gas?
sublimation
Is sublimation a exothermic or endothermic?
endothermic
What are the starting and ended phases for sublimation?
Sublimation is the transition from solid directly to gas without passing through a liquid phase (e.g. dry ice is solid carbon dioxide at very low temperatures which sublimes into carbon dioxide gas).
What is a sentence for sublimation?
Here is an example sentence with the word "sublimate":Dry ice will sublimate into carbon dioxide when it is kept at room temperature.
