Yes. A change of phase is a type of physical change.
The heating of wax is an example of a physical state change. The wax melts from a solid to a liquid and then freezes back to a solid again. Keep in mind, however, that some of the wax is actually burning, and that portion is undergoing a chemical change.
Because only its appearance changed, not what it is
If you plaster it back its original form,it'll harden and be the same...though i think it will be harder to melt .
i believe that is correct, yes changing something from a solid to a liquid would be a physical change, yes
Changing from a solid to a liquid is a physical change. The chemical composition of the wax does not 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.
Physical change. The wax was solid and now it is a liquid. All phase changes are physical changes.
The melting of the wax is a physical change. The burning the of wick is the chemical change
Physical change.
A physical change does not create a different chemical compound. Grinding a brick into a fine powder is a physical change. Freezing water is a physical change. Melting wax is a physical change.
Melting is a physical process.
Melting candle wax is a chemical change. Why? Because when you cook or burn candle wax it melts so it is a chemical change.
no because the wax will always stay the same. it is a physical change
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.
