How Does A Burning Candle Show Chemical And Physical Changes. The heat of the flame vaporizes the liquid wax (turns it into a hot gas), and starts to break down the hydrocarbons into molecules of hydrogen and carbon. Since it again turns into solid. In a burning candle, wax is drawn up the wick by capillary action and evaporates, so what is burned is a gas. The heat of the flame produces an updraught of air that draws the flame into its familiar shape. This liquid wax is then drawn up the wick by capillary action. Chemical changes are frequently harder to reverse than physical changes. When a candle is lighted, some of the solid wax first melts and turns into liquid, then it turns into vapours to produce a flame. Clarify the ideas of burning, melting and evaporating with your students and tackle some misconceptions about candles with this lesson. On heating, candle wax melts and form liquid wax. Physical changes in burning candle: One good example of a chemical change is burning a candle. When you light a candle, the heat of the flame melts the wax near the wick. In zero gravity there is no ‘up’ and a flame forms a sphere. It is a physical change.
