What chemical changes occur when a candle burns?
So, the melting of wax and vapourisation of melted wax are physical changes. Chemical Changes : The wax near flame burns and gives new substances like carbon dioxide, carbon soot, water vapour, heat and light
Is burning a wax candle a chemical change?
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? The process of burning (as opposed to evaporating) is a chemical reaction, a chemical change.
What type of change is burning of candle wax?
– Chemical change is observed when the wax melts near the flame and converts into wax vapour (change of state is observed), the liquid wax vaporized into vapour form near the flame, and also the chemical energy is converted into light heat energy as we
Is burning of candle a physical change or chemical change?
Additional information: On heating, candle wax melts and forms liquid wax. So, it is a physical change in the burning of candles. Since, it again turns into solid wax on cooling. This is a reversible change.
