iv. Melting
The correct option is D i, ii and iv
- Boiling is the vaporization of the liquid when it is heated to its boiling point.
- Sublimation is the transition of a substance directly from solid state to gaseous state without passing through liquid state.
- Condensation is the reverse of evaporation, i.e. change in the physical state of a substance from gaseous state to liquid state.
- Melting is the transition of a substance from solid state to liquid state.
Boiling, Sublimation and Melting occur when heat is absorbed by the matter and condensation occurs when heat is released by the matter.
