Sublimation is the phase transition of a substance directly from the solid state to the gaseous state without passing through the intermediate liquid state upon heating. Similarly, the reverse process is called deposition. Two common examples of sublime substances are ammonium chloride ($NH_4Cl$), camphor, naphthalene balls, and solid carbon dioxide (dry ice).
