Define sublimation
1 answer
Sublimation refers to the process where a substance changes directly from a solid state to a gas state without passing through the liquid state. In this process, the solid substance bypasses the melting phase and undergoes vaporization instead. Sublimation occurs when the atmospheric pressure is lower than the substance's vapor pressure at a specific temperature. Examples of substances that undergo sublimation include dry ice (solid carbon dioxide) and mothballs (naphthalene).
