Sublimation is a process where a substance transitions directly from the solid state to the gas state without passing through the liquid state. This occurs under specific conditions of temperature and pressure. A common example of sublimation is dry ice (solid carbon dioxide) turning into gas at room temperature.
In terms of the state of matter, sublimation involves the solid state and the gas state. The substance starts as a solid and ends up as a gas, bypassing the liquid phase entirely. This phenomenon is unique and depends on the substance’s properties and environmental conditions.
