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).
Green residue on the wick could indicate that the candle contains impurities or additives that are burning off. It could also be a sign of the candle burning unevenly, which may be caused by the wick being too long or the candle being exposed to drafts. It's best to trim the wick and avoid burning the candle in a drafty area to prevent this issue.
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!
Smoke gets its color from the particles and chemicals present in the burning material. For example, black smoke from burning wood contains carbon particles, while white or gray smoke from burning paper may contain water vapor and other chemicals. The color of smoke can also be influenced by the temperature and amount of oxygen present during the combustion process.
No, the heat from a burning candle is not matter; it is a form of energy. Matter consists of substances that have mass and occupy space, while heat is the energy transferred between objects due to a temperature difference. The heat generated by the candle results from the combustion of the wick and wax, which produces both thermal energy and light.
You can play the game "flames candle" by lighting a candle and taking turns blowing it out while asking questions about your future with someone. Each time the candle is successfully blown out, a letter from the word "flames" is crossed off. The remaining letters will reveal your relationship status with that person.
Black smoke-you are burning oil, engine is worn out. White smoke-you probably have a blown head gasket. Good luck with either one, both are expensive to repair. The above answer is only partially correct. Black smoke is not oil burning. Black smoke is an overly rich fuel mixture. Blue smoke is burning oil and white smoke is coolant in the combustion chamber.

1. Crushing is a physical process.2. Burning is a chemical process.

A burning candle involves both physical and chemical changes. The physical change is the melting of the wax, while the chemical change is the wax combining with oxygen in the air to produce heat, light, carbon dioxide, and water vapor.
If it's for good it means it's working against the negativity that was directed towards you. If it was meant for harm towards another it means they are protected and if it continues to burn black it would backfire on you.

Typically, white smoke after sitting over night is just steam from condensation or moisture in the air. However, thick white smoke while at operating temp is an indication that you are burning anti-freeze. You may have a blown head gasket if this is the case. Over filling oil can cause a white/blue smoke as well.
