Why Is Burning Candles A Chemical Change. Water vapor and carbon dioxide gas dissipate in the air around the candle in a reaction that also yields light and heat. In a burning candle, wax is drawn up the wick by capillary action and evaporates, so what is burned is a gas. As this warm air moves up, cooler air and oxygen rush in at the bottom of the flame to replace it. The heat of the flame produces an updraught of air that draws the. The act of burning paper actually results in the formation of new chemicals (carbon dioxide and water, to be exact) from. When a candle burns, the flame heats the nearby air and starts to rise. This is because the wax oxidizes or burns to yield water and carbon dioxide. A physical change is a change in matter that alters its form but not its chemical identity. 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?. Mixing baking soda and vinegar. When you burn a candle, you end up with less wax after burning than you started with. One good example of a chemical change is burning a candle. When that cooler air is.
