Sublimation is the change from which state to which?

Explanation:
Sublimation is the change from a solid directly into a gas. In sublimation, the solid doesn't melt into a liquid at all; the particles gain enough energy to break free from the solid’s structure and become a gas. Dry ice turning into carbon dioxide gas at room temperature is a classic example. This differs from melting (solid to liquid), evaporation or boiling (liquid to gas), and deposition (gas to solid).
