if you left a block of dry ice in a bowl at room temperature all day what would happen to it

Answer 1

If you left a block of dry ice in a bow of room temperature all day, it would evaporate. Dry ice is a substance that undergoes sublimation - instead of going from it’s solid form to a liquid form, and then to its gaseous form, it goes straight from its solid form to its gaseous form. So, over the course of the day, it would slowly evaporate from dry ice to gaseous carbon dioxide.

Answer 2

If you left dry ice(which is solid carbon dioxide) in a bowl it would sublimate. Which is going straight from a solid state to a gaseous state without going through the liquid phase. The dry ice will gradually disappear as it turns into gas. You will see fog around it because the water vapor in the air(heat from it's surroundings) condenses on the cold carbon dioxide gas. Hope this helps!
