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....
What else can I help you with?
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 dry ice sublime exothermic?
Yes, the process of dry ice sublimation is exothermic. When dry ice (solid carbon dioxide) changes directly into gas without passing through the liquid phase, it releases heat energy, making it an exothermic process.
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.
Sublimation is a change of state from a solid directly to a what?
Sublimation is a change of state directly from a Solid to a Gas, or a Gas to a solid. There is no intermdiate liquid stage. Carbon dioxide ( gas) sublimes to Dry Ice (Solid Carbon dioxide).
What phase is carbon dioxide in at - 20 degrees Celsius and 1 ATM pressure?
At -20 degrees Celsius and 1 ATM pressure, carbon dioxide is in the solid phase (dry ice), as it undergoes direct sublimation from a gas to a solid at temperatures below its sublimation point.
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 dry ice sublime exothermic?
Yes, the process of dry ice sublimation is exothermic. When dry ice (solid carbon dioxide) changes directly into gas without passing through the liquid phase, it releases heat energy, making it an exothermic process.
What is it called when dry ice converts into carbon dioxide gas?
Sublimation. Dry ice, which is solid carbon dioxide, changes directly into carbon dioxide gas without passing through a liquid phase.
Is carbon dioxide formation endothermic and exothermic?
Exothermic because the heat of formation is -566. Exo- is negative and Endo- is positive.
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 a?
The solid carbon dioxide is transformed directly in gaseous carbon dioxide; this phenomenon is called sublimation.
What is the physical change of carbon dioxide and snow disappears?
The physical change that is happening is called sublimation. Sublimation is when a solid (snow) directly turns into a gas (carbon dioxide) without passing through the liquid state.
When a chunk of dry ice is at room temperature a cloud of carbon dioxide vapor forms The carbon dioxide is changing from?
The carbon dioxide is changing from a solid to a gas directly through a process called sublimation. Dry ice is solid carbon dioxide at a temperature of -78.5°C, and when it warms up to room temperature, it sublimes into carbon dioxide gas without passing through the liquid phase.
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
Is dry ice exothermic?
Dry ice sublimation (changing from solid to gas) is an endothermic process because it requires heat energy to break the intermolecular forces holding the solid together. However, when dry ice sublimates in an enclosed space, it can release cold temperatures and feel cold to the touch, but this is due to the removal of heat energy from the surrounding environment, not due to an exothermic reaction.
