Question

Dry ice changes from a solid directly into a gas at room temperature. Sublimation is the transition of a substance directly from the solid to the gas phase without passing through an intermediate liquid phase. What does sublimation demonstrate

Answer 1

Answer:

The process in which a solid changes directly to a gas is called sublimation. It occurs when the particles of a solid absorb enough energy to completely overcome the force of attraction between them. Dry ice (solid carbon dioxide, CO2) is an example of a solid that undergoes sublimation.
