Can you reverse the change?
Burning is a chemical reaction, an oxydation.
It constituen carbon and hydrogen converted into CO2 and H2O. It is the chemical change of candle
It is a chemical change.
chemical
It is a chemical change.
It is a physical change because when it melts it is still a candle just a melted one
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!
That is correct, a candle (or the material of which it is composed, which is usually paraffin) undergoes a chemical change when it burns.
The chemical change in a lit candle is called combustion. Combustion is a rapid chemical reaction between oxygen in the air and the fuel (in this case, the wax in the candle) that produces heat, light, and carbon dioxide.

The melting of a candle is a physical change. It involves a change in state from solid to liquid due to the absorption of heat energy, without any change in the chemical composition of the candle wax.
Burning a candle is a chemical change because the wax undergoes a chemical reaction with oxygen in the air to form new substances like carbon dioxide and water. This process results in the candle getting shorter as it burns.
