Answer 1

Explanation:

When wax melts in the sun then this phenomenon is called melting. When solid state of matter changes directly into vapour state without undergoing liquid state then this phenomenon is known as sublimation.

Evaporation

Evaporation is a surface phenomenon. Water from the surface of the clothes gets evaporated. Thus, evaporation occurs during drying of wet clothes.

Formation of clouds takes place because of condensation. Condensation takes place when the water that has evaporated changes back to liquid state and condenses in the upper layers of the atmosphere forming clouds.
