What physical and chemical changes occur when a wax candle burn?

When the wax candle burns, the wax which melts can be changed to its solid state on cooling, which is a physical change. The burning of wax releases some gases which cannot be reversible. Hence it is a chemical change.

Does the mass of the ingredient change during physical changes what about chemical changes?

Physical changes are like cutting paper. The mass does not change. Chemical changes do not change total mass either. If you put a candle in a sealed container so that you may measure the total mass of the candle and the air before burning, then light the candle electrically but keep everything sealed, the total mass after burning will still be the same. But if you measure only the candle, then its mass has changed. So the mass of one single 'ingredient' will change during a chemical change.

What kind of changes take place when a candle is lit or burned Explain?

When a candle is burnt a physical AND chemical change takes place. Its a physical change when the wax is being melted because the chemical structure has not change, meaning it cannot be a chemical change. Its also a chemical change because you are burning the string. When you burn something the chemical structure DOES change, meaning it is a chemical change.

Is burning a candle a chemical change?

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)

Why burning of a candle is both a physical change and chemical change?

The 'melting' is physical, the 'burning' is chemical.
