Do Sublimation and boiling both happen at the surface of the substance.?
False
Is the sublimation of carbon dioxide exothermic?
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....
Will sublimation occur for all substances if the pressure is correct?
Yes it is. Dry ice, or liquid carbon dioxide, is a classic example because it does not go through the liquid phase. The opposite of sublimation is deposition (gas to solid).
What is the change of state from liquid to gas at the surface of a liquid?
When a liquid changes to a gas below its surface as well as at the surface, the liquid is at a temperature equal to or greater than its boiling point.
What will happen to Styrofoam balls in boiling water?
No it does not

False
Do sublimation and boiling both happen at the surface of the substance?
False
What may happen to the boiling point of a substance if there are impurities present?
The boiling point won't decrease
What are the changes?
Sublimation, boiling, condensation, melting and freezing. One might include evaporation, though that does not happen at a particular temperature.
What are the different changes?
Sublimation, boiling, condensation, melting and freezing. One might include evaporation, though that does not happen at a particular temperature.
How does water evaporate without boiling?
A substance does not turn into water when it evaporates. Evaporation is when a substance goes from a liquid to a gas. A substance has to be a liquid to evaporate otherwise it is called sublimation, which is when a solid becames a gas.
What are the different phases change?
Sublimation, boiling, condensation, melting and freezing. One might include evaporation, though that does not happen at a particular temperature.
What process can happen when a substance changes from a liquid to a gas?
The phenomenon associated with the change of a substance from a liquid to a gas is called boiling. Of course, a liquid can also evaporate without boiling, which is slower and harder to observe.
What will happen to bring a substance from a liquid to a gas?
To bring a substance from a liquid to a gas, it needs to undergo the process of vaporization or boiling. This occurs when the substance is heated to its boiling point, which is the temperature at which its vapor pressure becomes equal to the atmospheric pressure. As the substance absorbs heat, its particles gain energy and become more volatile, transitioning from the liquid phase to the gas phase.

What may happen to the boiling point of the substance if there are impurities present?
The boiling point will increase. The impurities essentially "block" the molecules of the substance from leaving the liquid as a gas, so a higher temp is needed to boil it. see colligative properties.
What may happen to the boiling point of a substance if there are impurities present. Explain in terms of the nature of impurities.?
it might decrease or increase depends on the impurities added.:D
