Solution

When the candle burns,

wax $⟶ {C O}_{2} +$ heat $+$ light
(vapours)

This is a chemical change, it can't be reversed. Whereas, melting of wax is a physical change.

${w a x}_{(e)} ⇌ w a x (s o l i d)$

When molten wax cools it solidifies again.

Another example of a process in which both physical and chemical changes take place is the digestion of food.

Physical change $⟶$ Breaking down of larger food particles into smaller particles
Chemical change $⟶$ Digestion of food
