When candle wax melts, it is only changing its physical state from a solid to a liquid. Its chemical makeup doesn't change. When the wax cools, it returns to its solid state. Since only its physical state is changed, melting candle wax is a physical change.
Solid wax and liquid wax are still wax, so they are chemically the same, but physically different.
Because there is no electron interaction between elements that would mark a chemical change. The wax is just changing states; solid to liquid. It is not changing in basic composition.
Melting candle wax is a chemical change. Why? Because when you cook or burn candle wax it melts so it is a chemical change.
It is a physical change, from a solid to a liquid. The chemical composition of the wax remains unchanged.

Physical change. The wax was solid and now it is a liquid. All phase changes are physical changes.

Melting is a physical process.
no because the wax will always stay the same. it is a physical change

Yes it is!:Pwhen a candle is lighted the solid wax changes into liquid wax,then it turns into vapour to produce flame.new substances like Co2 and H2O are formed alongwith the evoulation of light and heat.

freezing of water, boiling of water and melting of wax
The melting of the wax is a physical change. The burning the of wick is the chemical change
