What Things Can Sublimate?

These are some common substances that undergo sublimation upon heating under the normal atmospheric pressure condition.

  • dry ice (solid CO2, carbon dioxide)
  • Ice & snow ( from Water )
  • iodine crystals.
  • Naphthalene (mothballs) Naphthalene – Wikipedia.
  • Camphor.
  • Caffeine ( under vacuum )
  • Arsenic.
  • Phthalic Anhydride.

What substances can sublimate?

A number of solids are capable of sublimating at normal temperatures and pressures, including snow, iodine, arsenic, and solid carbon dioxide (dry ice). Sometimes other materials can be made to sublimate by creating low pressure conditions.

What are 3 examples of sublimation?

To help you gain a better understanding of this process, here are some real-life examples of sublimation:

  1. Dry Ice. As mentioned earlier, dry ice is one of the most popular examples of sublimation in real life.
  2. Water.
  3. Specialized Printers.
  4. Moth Balls.
  5. Freeze Drying.
  6. Air Fresheners.

What is a good example of sublimation?

Through sublimation, a substance changes from a solid to a gas without ever passing through a liquid phase. Dry ice, solid CO2, provides a common example of sublimation. It is also possible for ice to sublimate, though it requires specific weather environments and high altitudes.

Why do some things sublimate?

The vapor pressure of any substance increases as temperature rises. Solids too, not just liquids. Sublimation happens when the total pressure of the atmosphere is less than the vapor pressure of compound, and melting has not happened yet because it is not hot enough. Different compounds have different vapor pressures.
