Is there a boiling analog to sublimation?

In summary, liquid water and ice can both evaporate under specific conditions, with boiling being an extreme form of evaporation. Boiling occurs when the saturated vapor pressure of a liquid equals atmospheric pressure. Dry ice also exists on this line, but boiling is more violent for liquid water due to its physical arrangement.

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...
 

Related to Is there a boiling analog to sublimation?

1. What is sublimation and how is it different from boiling?

Sublimation is the process by which a solid directly turns into a gas without going through the liquid phase. Boiling, on the other hand, is the process by which a liquid turns into a gas through the application of heat. The main difference between the two is that sublimation skips the liquid phase, while boiling requires a liquid phase.

2. Is there a boiling analog to sublimation?

Yes, the boiling analog to sublimation is called "deposition". Deposition is the process by which a gas directly turns into a solid without going through the liquid phase. This is the reverse of sublimation.

3. What are some common examples of sublimation?

Dry ice (solid carbon dioxide) sublimes into carbon dioxide gas at room temperature. Mothballs (solid naphthalene) also sublime into gas at room temperature. Snow and ice can also sublime under certain conditions, such as in high altitudes where the air pressure is lower.

4. Can sublimation occur at any temperature?

No, sublimation can only occur at a specific temperature and pressure. This is known as the sublimation point. Above this temperature and pressure, the substance will turn directly into a gas. Below this point, the substance will remain in its solid phase.

5. How does sublimation impact the preservation of food?

Sublimation can be used to preserve food by freeze-drying. This process involves freezing the food and then placing it in a vacuum chamber where the frozen water in the food sublimes into gas, leaving behind a dehydrated food product. This method can extend the shelf life of food and preserve its flavor and nutrients.
