Burning of candle involves both physical and chemical changes
Explain

Kirti Gogia · Accepted Answer

Candle is made up of a solid block of wax with a wick embedded
in it
1) Physical Change
When candle is lit, the heat of the flame melts the solid wax to
liquid wax This signifies a physical change from solid state to
liquid state Also, as the wax melts, the size of the candle
decreases It then solidifies and takes a different shape
2) Chemical Change
The wax acts as a fuel when we light the candle and is basically
carbon The carbon combines with oxygen to form another chemical
substance, carbon dioxide and water Also the unburnt carbon is
deposited as black substance called soot This signifies a chemical
change

Burning of candle involves both physical and chemical changes. Explain.
