  • Sublimation: Understanding Substances That Transform from Solid to Gas
    This describes a substance that undergoes sublimation.

    Here are some examples:

    * Dry ice (solid carbon dioxide): This is the most common example. Dry ice sublimes at room temperature and atmospheric pressure.

    * Iodine: You can see this happening when you heat solid iodine in a test tube. The purple vapor is a good indication of sublimation.

    * Camphor: A common household moth repellent, camphor also sublimes.

    * Naphthalene: Another moth repellent, naphthalene also sublimes.

    Let me know if you'd like more information about sublimation!
