Is candle burning physical change?
Physical change means change physically while chemical change means change chemically or change in chemical properties.Like if you would drop a chip of zinc in sulphuric acid it will its color will be changed which is no doubt a physical change.But,also its properties are changed as it will be transformed into zinc sulphate from simple zinc,thus it also undergoes a chemical change. 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!
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 answerIt 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).
