Answer 2

Hey Student,

◆ Interconversion of states -

Melting -

• When solid wax candle is heated, it melts to liquid state.

Evaporation -

• When liquid wax around tip is heated some more, it gets converted to vapour.

Solidification -

• Liquid wax on the side when cools off, it gets converted to solid state.

Sublimation -

• Solid wax is directly converted to vapour form by the process of sublimation.

Hope this helps you...
