Substances undergo sublimation or deposition based on their vapor pressure and temperature conditions. If the vapor pressure of the solid exceeds that of the liquid phase at a given temperature, sublimation occurs; if the vapor pressure of the gas decreases ...

One example of a substance that undergoes sublimation is dry ice, which is solid carbon dioxide. When exposed to room temperature, dry ice sublimes directly into carbon dioxide gas.
Deposition is the direct change of state from gas to solid without passing through the liquid state. It differs from sublimation in that it involves the direct transition from gas to solid.
Sublimation occurs when a substance transitions directly from its solid state to its gaseous state without passing through the liquid state.
The direct change of state from solid to gas is called sublimation.
