Why Is A Burning Candle A Chemical Change. Burning is a physical change because the physical changes in the candle is that the wax melts, then freezes back into solid state again, and the chemical changes are that the wick burns, soot, and smoke. When a candle burns, there is both a physical and chemical reaction.

When a candle burns, both physical & chemical changes occur. The physical change is quite obvious and in fact, it can be. Physical changes in burning candle:
This Is A Reversible Change.
A burning candle produces wax vapours which solidify and form wax again is physical change. So, this is the chemical change part of the burning of a candle. The melting of a candle is physical change as no new product is formed.
Chemical Changes In Burning Candle:
Hence burning of candle shows both physical and chemcial changes. When a candle burns, both physical & chemical changes occur. When a candle burns, there is both a physical and chemical reaction.
When A Candle Is Burnt In Air, The Mass Of The Product Is Increased Due To Atmospheric Oxygen Which Combines With The Carbon And Hydrogen Of The Candle Wax During Burning To Produce Water Vapour And Carbon Dioxide.
Chemical changes in burning candle: Water vapor and carbon dioxide are formed. The oxygen is from the atmosphere, the spark is the.
Moreover, The Change Is Irreversible As The Initial Substance Cannot Be Recovered By Any Means.
The liquid wax vaporizes due the heat produced by the flame. This wax vapor near to flame burns and gives new substances like carbon dioxide, carbon soot, water vapours, heat and light. When candle burns, wax in candle converts from solid into liquid this is a physical change (as it is a change in state of matter and can be reversed) however, wax near the flame burns and convert into carbon dioxide this carbon can’t be again converted into wax , so this is a chemical change.
When You Light The Candle, The Wax Present Near The Wick Will Melt.
Hydrocarbons are molecules made from hydrogen and carbon.burning the wax pulls the hydrogen and carbon in the wax apart and recombines them with oxygen from. Burning is a chemical change that involves oxidation thus producing heat and light. Burning is a physical change because the physical changes in the candle is that the wax melts, then freezes back into solid state again, and the chemical changes are that the wick burns, soot, and smoke.
