The summary is that "There are more than fifty individual characteristics that can be identified, solely by observation, of a burning candle."
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.

That is correct, a candle (or the material of which it is composed, which is usually paraffin) undergoes a chemical change when it burns.
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.
It is a chemical change.
What are the physical properties of unlit candle

Heat and light energy.
A candle utilizes chemical energy stored within the wax. When the candle is burned, this chemical energy is converted into light and heat energy.

Chemical energy is converted to light and thermal energy.
It is a chemical change.
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 energy of a candle comes from the chemical reactions that occur when the candle burns. This process releases heat and light energy in the form of a flame. The energy produced by a candle can be used for lighting or heating purposes.
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.
