Heating a candle causes its wax to melt and burn, which involves a chemical reaction where the wax molecules are broken down and combine with oxygen in the air to produce heat, light, water vapor, and carbon dioxide. This transformation of wax into different compounds is a chemical change, as the composition of the candle wax is altered irreversibly during the process.
What else can I help you with?
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
Is a candle melting chemical or physical?
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.
How is a burning candle both physical and chemical changes?
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.
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 heating KClO3 and MnO2 a chemical or physical change?
Heating KClO3 and MnO2 to form KCl and MnO2 is a chemical change as new substances are being produced.

What is energy of a candle?
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.
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!
when a candle is lit it undergoes a chemical change?
That is correct, a candle (or the material of which it is composed, which is usually paraffin) undergoes a chemical change when it burns.
What is the chemical change called in a lit 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.
How do you know if a candle is a chemical change?
Can you reverse the change?
When the wick burns and the candle melts is it a chemical or physical change?
it is a chemical change
Is a candle melting chemical or physical?
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.
Heating a frying pan is chemical or physical change?
Heating a frying pan is a physical change. A chemical change is when you change the chemical properties. Heating the pan is only changing the temperature of the pan not the chemical make up.
