Yes, burning a candle is a chemical change. New chemical compounds are being formed as the reaction continues. The paraffin in the candle is a hydrocarbon chain, and it is "breaking down" chemically using oxygen from the air to form (idealy) carbon dioxide and water. But there are also physical changes that take place at the same time.
Phenomena during the candle burning:
- melting (physical phenomenon)
- evaporation (may be considered a chemical but also a physical phenomenon)
- oxydation - reaction with oxygen, burning (chemical phenomenon)
- thermal decomposition (chemical phenomenon)

Is burning candle getting shorter physical or chemical change?
Burning a candle is a chemical change. It cannot be "unburnt"
What is burning candle it is physically Chang or chamically?
Burning a candle is a chemical change, as is burning anything.
Is burning a candle a chemical change or a physical change give reason?
It is both a physical and chemical change. The burning of the wick s chemical while the candle melting being physical.
How we know a chemical change has occurred when burning a candle?
Burning is a chemical reaction, an oxydation.
What are the steps to prove that a burning of a candle is physical as well as a chemical change?
1. Melting of the candle is a physical change. 2. Burning and thermal decomposition are chemical changes.
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 is the chemical change when a candle is alight?
Burning of the wick or candle material, thermal dissociation of candle material.
How is a burning candle both physical and chemical changes?
because of the digestions system of the candle is visible
Is a candle burning a physical change?
It is actually both. The burning of the wick involves a chemical change. The physical change is the wax.
Why burning candle is chemical change?
It is a chemical change because the burning thread is combusted. The combustion is an oxidation reaction. Most importantly, it is a chemical change because after burning, the chemical properties of the thread is changed entirely!
How does a burning candle show both of chemical and physical change?
because it can
A candle is 10 inches high is it a physical or chemical change?
it doesn't matter how high it is, if its burning, its a chemical change
