Yes it is!:P
when 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.
No. Just as ice that melts is still water, the wax is being heated up past its melting point and it can't hold itself together anymore as it is now a liquid.
Melting is a physical change, not a chemical change.
Freezing is a physical change.
- Melting is a physical change.
physical
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
The dissolution of sodium chloride is considered as a physical process.
This is a physical change, not a chemical change! It is because all the wax is still all there as for if it was a chemical change it would be all gone!Physical. Its physical state changed from solid to liquid. It's chemical make up remains the same.Melting wax is a chemical change because a new substance is forming. Trust me im intelligent and we just learned this in science.physical change :)It is a chemical change because it gives off heat even when it is burning. heat is one of the signs that tell whether it is physical or chemical change. The signs are heat , light's ,gas,discolor.Melting was would be a physical change-- no chemical reaction occurs when something melts or boils. A burning candle is a chemical change, both can occur at the same time.
Physical change means change physically while chemical change means change chemically or change in chemical properties.Like if you would drop a chip of zinc in sulphuric acid it will its color will be changed which is no doubt a physical change.But,also its properties are changed as it will be transformed into zinc sulphate from simple zinc,thus it also undergoes a chemical change. Now,with your question,the candle breaks but the candle remains the candle,so,its not a chemical change but a physical change only.Hope it helps!

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.

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

Melting is a physical property because it only changes the physical state of the substance, such as wax, but does not change its physical or chemical properties. This is because melting is not a chemical reaction. Flammability, however, is a chemical property, and when a substance burns, that is a chemical reaction, and the physical and chemical properties of the products will be different than the reactants (starting substances).
