Does Ice Evaporate? Answers Here!

[Chaos' lil bro Order]

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 celsius is the freezing point of water and the melting point of Ice. Snow and Ice must be above 0 degrees celsius 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.

 

[St. Aegis]

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.
