Sublimation is the process where a substance changes directly from a solid to a gas without passing through the liquid state. Carbon dioxide (CO₂), especially in the form of dry ice, is a common example.Drawing guide:Solid CO₂ (dry ice):Draw closely packed CO₂ molecules (label them O=C=O).Arrange them in a neat, tight pattern.Sublimation arrow:Draw an upward arrow labeled “Heat” or “Sublimation”.Gaseous CO₂:Draw the same O=C=O molecules scattered and spaced far apart.Use motion lines to show they are moving randomly.
