Why does a candle smoke when it's blown out but not while it's burning?

you may not see it but once you blow out the candle, small embers are still inside the wick of the candle and burning. because the embers are so small thriving off the air particles thus creating the smoke you see.
Additional answer
It does smoke while burning, if you look closely enough. In fact, if you put a piece of glass or tin above the flame it will become blackened with smoke particles (carbon).

∙ 13y agoSmoke often contains partially burned material which is very flamable. This happens because nothing contains the fire as it is burning, and the hot gases rise, expand, and cool very rapidly, before they are finished burning.

The hot air around the candle is less dense than the cooler air and rises carrying the smoke from the candle with it. The smoke itself is comprised of heated particle which transfer their energy to the air and assist this process.

Now,with your question,the candle breaks but the candle remains the candle,so,its not a chemical change but a physical change only.Hope it helps!
