AI Thread Summary
Ice does not evaporate in the traditional sense, as evaporation refers to the conversion of liquid to vapor. However, ice can undergo sublimation, a process where it transitions directly from solid to gas under specific conditions of temperature and pressure. Sublimation occurs when ice is at low pressure and temperatures below the melting point of water, allowing it to change directly into vapor without first becoming liquid. Understanding the phase diagram of water is crucial, as it illustrates the boundaries between solid, liquid, and gas states, highlighting the conditions necessary for sublimation to take place.

Greetings, I was curious to know if ice evaporates. I suspect it does to a very slight degree but to what degree I am not sure. It likely depends on a plethora of factors, from ice temperature, outside temperature, humidity, sunlight, wind, etc. So if you have any leads for me I'd appreciate it, thanks.

Google "sublimation"
 
NO, 0 degrees Celcius is the freezing point of water and the melting point of Ice. Snow and Ice must be above 0 degrees celcius to melt to water and then the water will start to evaporate.

By definition, evapouration is the conversion of a liquid to vapour so technically no, but yes sublimation does occur.
 
at a certain pressure and a certain temperature, ice will nearly instantly change from the solid state to the gas state. I recommend looking at water's phase graph and see where on the graph it would happen. I believe the y-axis is pressure and x-axis is temperature. The graph should be divided into 3 regions, liquid, gas and solid. Look for the border between solid and gas and that is the region where sublimation occurs
 
Look up a "phase diagram" for water. See the point where the three lines meet? The region on the top left is where water's a solid (cold, high pressure). Top right is liquid (warmer, normal pressure). Bottom right is gas (warm, low pressure).

If you're at such a low pressure and cold temperature that you start off below the point where the lines meet (and you're still a solid), and you keep your pressure constant as you heat it up..you'll make the water go into sublimation without becoming a liquid.
 
Thread 'The Secrets of Prof. Verschure's Rosetta Stones'
(Edit: since the thread title was changed, this first sentence is too cryptic: the original title referred to a Tool song....) Besides being a favorite song by a favorite band, the thread title is a straightforward play on words. This summer, as a present to myself for being promoted, I purchased a collection of thin sections that I believe comprise the research materials of Prof. Rob Verschure, who at the time was faculty in the Geological Institute in Amsterdam. What changed this...
