A burning candle is an example of a what chang Physical or chemical?

Answer 1

Both. The wax melts to a liquid. The liquid passes up the wick by capillary action. The wax either volatilizes to a vapor (physical) or pyrolyzes in the heat to combustible compounds (chemical). The fuel then combines with oxygen to generate carbon dioxide and water (chemical). You should look up Michael Faraday's lectures on the chemistry of a candle.

Answer 2

I would say chemical - it is combustion.

The solid wax melts to form a pool of liquid wax. The liquid wax is drawn up the wick where it is heated by the flame to form a gaseous wax. This gas reacts with oxygen within the flame to form carbon dioxide and water vapour.

I suppose you could argue physical too, there is a change of state from solid--->liquid--->gas.

Answer 3

depends on if you are talking about the wax or the wick. the wax is undergoing a physical change while the wick is undergoing a chemical change(burning).

Answer 4

a Physical change.
The chemical component of the candle does not change

Answer 5

Chemical. Its a combustion reaction.

Answer 6

both
chemical change because the wick is burning
physical change because the wax is melting
