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....
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).
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.
No it does not

The boiling point won't decrease
Sublimation, boiling, condensation, melting and freezing. One might include evaporation, though that does not happen at a particular temperature.

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.

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.
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.

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.
it might decrease or increase depends on the impurities added.:D
