There are multiple physical changes and chemical changes that occur when a candle burns. One physical change is that the candle melts back into liquid wax. One chemical change is flame burning on the wick.

∙ 12y agoPhysical changes:
- most of the wax melts (becomes liquid) and then resolidifies
- some of the wax components vaporize (evaporate)
Chemical changes
- oxidation of the wick and volatile compounds from the wax (what actually burns)
- thermal decomposition of some of the heated wax

The chemical change is in the candle burning.

How is a burning candle both physical and chemical changes?
because of the digestions system of the candle is visible
Is a candle melting a physical change or a chemical change?
It is a physical change because when it melts it is still a candle just a melted one
What are the steps to prove that a burning of a candle is physical as well as a chemical change?
1. Melting of the candle is a physical change. 2. Burning and thermal decomposition are chemical changes.
Is candle wax melting physical property?
Melting candle wax is a chemical change. Why? Because when you cook or burn candle wax it melts so it is a chemical change.
Is candle wax melting chemical or physical change?
It is a physical change, from a solid to a liquid. The chemical composition of the wax remains unchanged.

Burning a candle is a chemical change. It cannot be "unburnt"
When the wick burns and the candle melts is it a chemical or physical change?
it is a chemical change

Is candle burning physical change?
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!

It is both a physical and chemical change. The burning of the wick s chemical while the candle melting being physical.
