- CHEMICAL CHANGE
- When a candle is burnt in air, the mass of the product is increased due to atmospheric oxygen which combines with the carbon and hydrogen of the candle wax during burning to produce water vapour and carbon dioxide.All these factors prove that the burning of a candle is a chemical change.
