When dry ice sublimates at room temperature does it create pressure?

Answer 1

If the gas isn't able to freely escape, such as in a closed container, then the answer is yes.

Answer 2

Yes, when dry ice sublimates at room temperature, it can create pressure if contained in a sealed space. This is because the sublimation of dry ice produces carbon dioxide gas, which can build up pressure if not allowed to escape. It is important to handle dry ice properly to avoid dangerous pressure build-up.
