Burning is a chemical reaction, an oxydation.
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.
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
Candle burning is the process called oxidation. This is, it's the reaction that takes place when a gaseous material reacts with oxygen, the wax needs to change to gaseous state for the reaction to take place.

Burning a candle involves a chemical change, as the wax is being oxidized by the oxygen in the air to produce heat, light, carbon dioxide, and water vapor. This process is irreversible and results in the formation of new substances, which is characteristic of a chemical change.
It is actually both. The burning of the wick involves a chemical change. The physical change is the wax.
A burning candle involves both physical and chemical changes. The physical change is the melting of the wax, while the chemical change is the wax combining with oxygen in the air to produce heat, light, carbon dioxide, and water vapor.
because it can
When a candle burns, the wax undergoes a chemical reaction with oxygen in the air to produce heat, light, carbon dioxide, and water vapor. This process involves breaking and forming chemical bonds, resulting in a new substance being created. Therefore, burning a candle is considered a chemical change.
it doesn't matter how high it is, if its burning, its a chemical change
The melting of the wax is a physical change. The burning the of wick is the chemical change
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.
