SUMMARY

Ice does not evaporate in the traditional sense; instead, it undergoes sublimation, transitioning directly from a solid to a gas under specific conditions of temperature and pressure. The discussion highlights that sublimation occurs when ice is subjected to low pressure and temperatures below the triple point of water, as illustrated in a phase diagram. Key factors influencing this process include temperature, pressure, and environmental conditions such as humidity and wind. Understanding the phase diagram of water is essential for visualizing these transitions.

PREREQUISITES
  • Understanding of phase diagrams, particularly for water
  • Knowledge of sublimation and its definition
  • Familiarity with temperature and pressure concepts
  • Basic principles of thermodynamics
NEXT STEPS
  • Research the phase diagram of water to understand sublimation conditions
  • Explore the concept of sublimation in various substances beyond water
  • Investigate the effects of pressure on the state changes of matter
  • Learn about the thermodynamic principles governing phase transitions
USEFUL FOR

Students of chemistry, physicists, environmental scientists, and anyone interested in the properties of water and phase transitions will benefit from this discussion.

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.
 
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.
