Is a burning candle a reversible or non reversible change?
Burning a candle is a non-reversible change because once the wax is melted and the wick is burnt, it cannot be undone to return the candle to its original state. The chemical composition of the wax and wick is changed permanently.
Is candle wicks burning a version of chemical change?
Yes, the burning of a candle wick is a chemical change because it involves a chemical reaction between the wick, wax, and oxygen in the air to produce light and heat, along with byproducts like carbon dioxide and water vapor. This process is irreversible and results in the formation of new substances.
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.
Why burning of candle is a physical and chemical change?
CHEMICAL
Why burning candle is chemical change?
It is a chemical change because the burning thread is combusted. The combustion is an oxidation reaction. Most importantly, it is a chemical change because after burning, the chemical properties of the thread is changed entirely!
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.
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
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!
Why is melting of covered candle a physical change while burning of a candle wick a chemical change?
This is because a candle will change its whole form and stay that way, which is a physical outer change. And a candle wick only burns, it doesn't change it's appearance.
Is the wick of a burning candle part of the chemical reaction?
Yes, the wick is also burned.
Is a burning candle a reversible or non reversible change?
Burning a candle is a non-reversible change because once the wax is melted and the wick is burnt, it cannot be undone to return the candle to its original state. The chemical composition of the wax and wick is changed permanently.
When the wick burns and the candle melts is it a chemical or physical change?
it is a chemical change
Is burning a candle wick a physical property?
No, burning a candle wick is a chemical change, not a physical property. Physical properties describe characteristics that can be observed without changing the substance's identity, while chemical changes involve the rearrangement of atoms and result in a new substance being formed.
Is a burning candle 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.

Is lighting a chemical change?
Yes. While act of melting wax is a physical change, because you can remould it, the wax is actually what is primarily burned as fuel. You cannot unburn the wick nor the consumed wax. Remember, if it can be redone, it is probably physical and vice versa.The wick of a candle is used to light it and is used as a medium for burning the wax. As the wax is heated, it is soaked into the burning wick. As the fire burns the wax on the wick, more melted wax is absorbed into by the wick. As the wax burns down, so does the wick.
