Verified Answer :

Sublimation is the direct transition of a solid to a gas. The opposite of that is deposition which is a gas cooling an becoming a solid. D) is the correct answer.

Answer: The correct answer is Option d.

Explanation: All these processes occurs as a change in phase. Sublimation is the process which occurs between the solid and vapor state. It is a process in which solid gets converted into gas phase.

\(Solid\rightleftharpoons Gas\)

Condensation process occurs between the states liquid and gases.  It is a process in which gas gets converted into liquid phase.

\(Gas\rightleftharpoons Liquid\)

Melting is the process that occurs between solid and liquid phase. It is a process in which solid gets converted into liquid phase.

\(Solid\rightleftharpoons Liquid\)

Vaporization process occurs between liquid and gas phase.  It is a process in which liquid gets converted into gas phase.

\(Liquid\rightleftharpoons Gas\)

Deposition process occurs between solid and gas phase. It is a process in which gas gets converted into solid phase.

\(Gas\rightleftharpoons Solid\)

Hence, the correct answer is option d.
