Burning of candles is an example of chemical change as well as physical change . Why is it so ? Explain .
Answers
Answer:
A change is defined as the physical change when there is no modification or alteration of the substance’s chemical composition happens. When a candle is burnt and the wax melts changing from solid to liquid state is referred to as physical change.
A change is defined as chemical when the composition of the material changes and new material is obtained different from the original one. Chemical changes are usually seen through the emission of gases, temperature changes, and precipitates.
Both physical and chemical change occurs when a candle burns. There are both reactions when the candle burns.
The physical change is quite often and can be seen clearly. When the wax melts slowly and the candle gets smaller and smaller. This is the physical change of the burning candle. This wax that melts slowly comes together back into solid and the sticks to the candle. This is also a physical change.
The chemical reaction, on the other hand, is less obvious and cannot be seen directly. The heat produced by the candle while burning consumes most of the oxygen around it plus the fuels which comes from the flames. When all this happens, it leads to the emission of carbon dioxide which is produced by the flames. These emissions of carbon dioxide should never be inhaled because it is not good for human health. This reaction is called chemical change.
Answer:
Burning of the candle is both physical and chemical change. Burning of candle melts the wax and hence physical state of wax has changed from solid to liquid. Again the wax combines with the atmospheric oxygen and changes to carbon dioxide, heat and light.
