Because the chemical composition is modified.
Melting is accompanied by burning and thermal degradation - two chemical reactions.
It is both a physical and chemical change. The burning of the wick s chemical while the candle melting being physical.
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!
The melting of the wax is a physical change. The burning the of wick is the chemical change
no because when a substance changes its state of matter then it is NOT considered a chemical reaction or a chemical 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.

because of the digestions system of the candle is visible
It is a physical change because when it melts it is still a candle just a melted one
1. Melting of the candle is a physical change. 2. Burning and thermal decomposition are chemical changes.
It is a physical change, from a solid to a liquid. The chemical composition of the wax remains unchanged.
It is both a physical and chemical change. The burning of the wick s chemical while the candle melting being physical.
chemicalBurning a marshmallow is a chemical change.

This is because a candle will change its whole form and stay that way, which is a physical outer change. And a candle wick only burns, it doesn't change it's appearance.
