Is there a boiling analog to sublimation?

Click For Summary
SUMMARY

The discussion explores the concept of boiling in relation to sublimation, specifically addressing whether ice can undergo a boiling-like process. It establishes that boiling occurs when the saturated vapor pressure of a liquid exceeds atmospheric pressure, while ice can evaporate without transitioning to liquid under similar conditions. The conversation highlights that boiling is characterized by the violent formation of bubbles, which is not applicable to dry ice unless subjected to specific heating methods that induce cracking.

PREREQUISITES
  • Understanding of phase transitions: evaporation, sublimation, and boiling

Liquid water sitting can evaporate without a problem, given that the vapor pressure surrounding it is less than the temperature dependent saturated vapor pressure. Similarly, an ice cube can also evaporate without becoming liquid under these same conditions. However, an extreme form of evaporation is boiling, when the saturated vapor pressure of liquid exceeds atmospheric pressure. Does this also exist with ice, and it is it just as violent and quick of a process?

Boiling is when the saturated vapor pressure of the liquid equals atmospheric pressure: it can't exceed atmospheric pressure and remain liquid. Dry ice exists on that line as well.

Boiling is "violent" not because of the chemical properties, but because of the physical arrangement of a pot of water: bubbles forming at the bottom of the pot have to go through the water to escape. You can't do that with dry ice except perhaps by putting a heating element inside a solid block and heating until it cracks...if it isn't porous...
