Describe the two changes that are seen when a candle burns.
Burning of the candle is a physical change and a chemical change.
Physical changes: On burning the candle, the wax slowly melts as the candle gets smaller and this molten wax can be again solidified and will make it into a candle which means that it is a reversible change.
Chemical changes: Heat is produced by the candle which consumes both the oxygen in an atmosphere, as well as the fuels coming from the flame. This will then lead to carbon dioxide emissions produced by the flame. This is an irreversible change.
