When a candle burns both physical and chemical changes occur?
In a burning candle, there are both physical and chemical changes. The melting of the solid wax to form liquid wax and the evaporation of liquid wax to form wax vapour are physical changes. The burning of the wax vapour is a chemical change. Likewise, when a candle burns both physical and chemical changes take place identify these changes?
Is the burning of wax a chemical change?
The burning of the wax vapour is a chemical change. Similarly, it is asked, why is lighting a candle a chemical change?
Is Burning a candle a reversible change in the atmosphere?
While burning the candle the wax slowly melts as the candle gets smaller and this molten wax can be again solidified and will make it into a candle.which means that it is a reversible change. The heat produced by the candle consumes both the oxygen in an atmosphere, as well as the fuels coming from the flame.
What happens to a candle when melted wax burns?
This reaction forms as the melted wax reacts with the fire and the surrounding environment to form what is very different from the original candle. The result is not totally related to the candle and cannot be reversed to go back to the original state of the candle. This change is so much negligible.
