In the lit candle, the chemical change occurs when the wax reacts with oxygen during combustion, producing carbon dioxide, water vapor, and heat, resulting in the candle burning down. The physical change is the melting of the solid wax into liquid as it is heated by the flame, altering its state without changing its chemical composition.
