Burning a candle involves both physical and chemical changes. The physical change is the melting of the candle wax as it is heated, while the chemical change is the combustion reaction of the wax with oxygen, producing heat, light, water vapor, and carbon dioxide.
New substances are being formed and old ones consumed, so this is a chemical change.
The melting of the candle wax is a physical change. The burning of the wick is a chemical change.
When a candle burns, both a physical and chemical change takes place. The melting of the wax is the physical change, whereas the chemical change is the combustion of the wax and the wick.
Burning of candle is both a physical as well as chemical change. Chemical because the wick is burned, which is a combustion reaction, and physical because the melting of the was is a physical change.
The melting of the wax is a physical change because you're just changing the form of the wax, not it's chemical properties. When you melt wax and it hardens, it's still wax, just in a different shape.
Burning is a chemical change. In a chemical change, new substances are formed - carbon dioxide and water. Melting wax is a physical change.
The melting of the candle wax is a physical change. The burning of the wick is a chemical change.
Burning a candle involves both physical and chemical changes.
The wick is burnt, so by definition involves a chemical change. Specifically, this is the reaction of the fibre and oxygen in the air forming carbon oxides and water.
The physical changes are the wax being melted and some of it vapourised; the same chemical change as above also takes place, as some of this vapour is burnt along with the wick.
New answer: the wax has to be vapourised in order to react with oxygen. The wick is just there to soak up the melting wax and lift it up to reach the oxygen. The flame is above the top of the candle: the vapourised wax is what is burning.
Chemical Change- is when something can not be changed back to its normal self
Physical Change- is when it can turn back in to its normal self
It is both. For the wick and some of the wax, it is a chemical change. They burn (oxidize) into carbon dioxide, water, and other compounds such as carbon monoxide.
For the rest of the wax, it is obviously a physical change. It melts and then become solid again as it cools. But there is less wax remaining than was present in the original candle. This wax was what provided the energy released by the candle.
It is a chemical change. Burning the candle wick converts it into CO2 and water when it reacts with the heat and oxygen in the air. The wax melting is a physical change.

Phenomena during the candle burning:
- melting (physical phenomenon)
- evaporation (may be considered a chemical but also a physical phenomenon)
- oxidation - reaction with oxygen, burning (chemical phenomenon)
- thermal decomposition (chemical phenomenon)
Chemical change. The candle was and the wick are getting burned meaning that the solid is turning into a gas. Of course any chemical change means that the look of the mater will change. It is a a chemical change and not a physical change because you can't turn the carbon dioxide it created back to its original state.
this is because a candle lives some wax as the string wastes away, which means the left over wax can then be made into another candle, with a new string of course which makes candle burning a chemical and physical change.
Both.
The wax melts which is a physical change and then the carbon atoms in the wax combine with oxygen which is a chemical change.

How is a burning candle both physical and chemical changes?
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.
What are the steps to prove that a burning of a candle is physical as well as a chemical change?
To prove that the burning of a candle is a physical and chemical change, you can observe the physical changes such as the melting of the wax and the formation of soot. Additionally, you can analyze the chemical changes by noting the production of carbon dioxide and water vapor during the combustion process. By observing both physical and chemical changes, you can demonstrate that burning a candle involves both types of transformations.
Is candle wax burning a physical change?
For the wax, yes. It changes to a liquid and then back to a solid. But some of the wax is also consumed in a chemical change as it oxidizes, along with the burning wick.
What is the physical and chemical change that occurs when a birthday candle is lit on a cake?
When a birthday candle is lit on a cake, the physical change that occurs is the wax of the candle melting into liquid form due to the heat. The chemical change involves the burning of the wax vapor to produce carbon dioxide and water vapor, along with heat and light.
Is a candle melting a physical change or a chemical change?
The melting of a candle is a physical change because it is a change in state from solid to liquid without altering the chemical composition of the candle.
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!
Is a candle burning a physical change?
It is actually both. The burning of the wick involves a chemical change. The physical change is the wax.
How is a burning candle both physical and chemical changes?
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.
What part of a burning candle takes place and physical change?
The melting of the wax is a physical change. The burning the of wick is the chemical change
How does a burning candle show both of chemical and physical change?
because it can
What are the steps to prove that a burning of a candle is physical as well as a chemical change?

By observing both physical and chemical changes, you can demonstrate that burning a candle involves both types of transformations.
Is burning candle getting shorter physical or chemical change?
Burning a candle is a chemical change because the wax undergoes a chemical reaction with oxygen in the air to form new substances like carbon dioxide and water. This process results in the candle getting shorter as it burns.
A candle is 10 inches high is it a physical or chemical change?
it doesn't matter how high it is, if its burning, its a chemical change
What is a real life process that fits into neither a physical or chemical change?
burning of candle
Is it a physical change when a candle changes size by burning?
Oh, dude, yes, it's totally a physical change when a candle burns and changes size. The wax is melting and then solidifying again as it cools down, so it's like a hot and cold dance party for the molecules. It's not like the candle magically grows or shrinks, it's just physics doing its thing.
Is candle wax burning a physical change?
For the wax, yes. It changes to a liquid and then back to a solid. But some of the wax is also consumed in a chemical change as it oxidizes, along with the burning wick.
What type of physical change will while crushing a rock and burning a candle?
1. Crushing is a physical process.2. Burning is a chemical process.
