Is a wax burning a reversible change?
No, burning wax is an irreversible change. When wax is burned, it undergoes a chemical reaction that changes it into different substances (carbon dioxide, water vapor, and heat) that cannot be easily reversed.
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 burning a reversible change prove it?
Yes, candle burning is a reversible change because it can be undone by extinguishing the flame. When the flame is removed, the wax solidifies again, demonstrating that the process of burning is reversible by cooling down the wax.
Can burning a candle be reversible?
No, burning a candle is not reversible. When a candle is burned, the wax is melted and the wick is consumed, resulting in irreversible changes to the candle's structure.
Is toast reversible or reversible?
Burning is an irreversible change.
Is logs burning a reversible or a irreversible change?
reversible
Is burning candle a reversible or irreversible change?
Burning a candle is an irreversible change because the wax undergoes a chemical reaction with the oxygen in the air, producing new substances like carbon dioxide, water vapor, and ash. Once the candle has been burned, it cannot be restored to its original state.
Name one reversible change when a candle burns?
The wax of the candle melts and then rehardens. This is a physical change and reversible
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.
Is burning wax a physical or chemical change?
Burning wax is a chemical change. If you are burning something, it will always be a chemical change.
Is a candle melting a reversible change or irreversible change?
The melting of a candle is a reversible change because the solid wax can be cooled and solidified again to form a new candle.
What physical and chemical changes occur when a wax candle burn?
Some wax burns, and as it does so, chemical changes occurs. Wax converts to CO2, CO, and H2O. That is an exothermic reaction The rest of the wax melts with the increased temperature. That is the physical change.
