Is A Candle Burning A Chemical Or Physical Reaction at Seth Eaves blog

Is A Candle Burning A Chemical Or Physical Reaction. One good example of a chemical change is burning a candle. When you burn a candle, you end up with less wax after burning than you started with. In a burning candle, wax is drawn up the wick by capillary action and evaporates, so what is burned is a gas. Chemical changes are frequently harder to reverse than physical changes. This is because the wax oxidizes or burns to yield water and carbon dioxide. All waxes are essentially hydrocarbons, which means they are largely composed of hydrogen (h) and carbon (c) atoms. Candles don't burn all by themselves. The size or shape of matter often changes, but there is no chemical reaction. If the wax was simply undergoing physical change, would you expect the candle to produce heat and light as it does when a candle burns? A physical change is a change in matter that alters its form but not its chemical identity. When you light a candle, the heat of the flame melts the wax near the. The heat of the flame produces an updraught of air that draws the flame into its.
