For the wax, yes. It changes to a liquid and then back to a solid. But some of the wax is also consumed in a chemical change as it oxidizes, along with the burning wick.

What is the physical and chemical change that occurs when a birthday candle is lit on a cake?
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.
Why burning of candle is a physical and chemical change?

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.

Candle wax is the fuel a candle uses to keep burning. So, I guess the effect of the wax is the candle keeps burning.
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.

It is actually both. The burning of the wick involves a chemical change. The physical change is the wax.

Is it a physical change when a candle changes size by burning?
Yes, because the candle wax isn't actually burning, just melting
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!

What physical and chemical changes occur when a wax candle burn?
Some wax burns, and as it does so, chemical changes occurs. Wax converts to CO2, CO, and H2O. That is an exothermic reaction The rest of the wax melts with the increased temperature. That is the physical change.
