That is a chemical change. Physical changes can be undone. Burning a bit of paper is another non-reversible change.
Because your $1,000 toaster is broken.....please buy a new one!! :)
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.
It is a chemical process.
Oxygen is the gas found in the air that is necessary for toast to burn. When toast is heated, it undergoes a combustion reaction where oxygen reacts with the toast to produce heat and light, resulting in the burning process.
Burning is an irreversible change.

because it can no be reversible once it has been burnt it cannot be turned back into bread or slightly toasted toast, that is its permanent form :D
reversible
Burning is an irreversible change.
No, it is not.

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.

Burning toast would be a chemical change. The bread would be changed into carbon and the reaction can not be reversed.
no it is'nt uyuyuyiuoukugtiutj
Burning is not reversible because it involves a chemical reaction that permanently changes the substances involved. Heating, on the other hand, is reversible since it involves providing energy to increase the temperature but can be reversed by removing the heat.
