The conversion of a solid directly into gas is called as :

- ENone of the above/More than one of the above
Show answer and explanation
Correct answer: (a) Sublimation
Explanation
Sublimation is the change of a solid directly into a gas, without becoming a liquid. Camphor, naphthalene, iodine and dry ice sublime.
The reverse, gas straight to solid, is deposition. Condensation is gas to liquid, and evaporation and boiling are liquid to gas.
