I have answer to your question:
Physical change = Melting of wax
the physical structure of wax changes when heated. It changes from solid to semi liquid or in jell form
The atoms of wax detach and the state of matter changes
Chemical change= Burning of wood
the wood when ignited have change of energy. wood initially have chemical energy stored initially. when burned this energy changes from chemical to heat energy

There are physical and chemical changes occurring when the wax is melted.
The melting from solid to the liquid form of wax and its evaporation into wax vapour is the physical change.
The chemical change is the burning of the wax vapour.
The wax vapour reacts with oxygen present in the air and forms new substances including ash and carbon dioxide.
