1. Dry Ice (Solid Carbon Dioxide): This is the classic example. Dry ice sublimates at room temperature, transforming directly from a solid to a gas without becoming liquid.

2. Napthalene (Mothballs): These are commonly used to deter moths, and they slowly disappear over time as they sublime.

3. Iodine: This element is a solid at room temperature, but it will easily sublimate into a purple vapor when heated.

4. Arsenic: This toxic substance also sublimates, making it difficult to contain and contributing to its dangerous nature.
