The burning of the match is irreversible because it cannot be undone. If the candle is made of regular wax and not the dripless kind, you can take the melted wax and make another candle out of it , just without a wick, which would have been destroyed in the first melting, making it an irreversible change as well.
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.
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.
Coffee dissolving, water boiling and chocolate melting are reversible physical transformations whereas wood burning is a chemical combustive transformation.
No, burning coal is an irreversible change as it involves a chemical reaction that transforms the coal into new substances such as carbon dioxide and ash. Once coal is burned, it cannot be reverted back to its original form.
The energy given off by burning a matchstick is mainly in the form of heat and light. The heat is a result of the exothermic combustion reaction that occurs when the matchstick is ignited, and the light is emitted as a by-product of the combustion process.

Burning is an irreversible change.
Burning of a matchstick.
No, it is not.
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.
That is a chemical change. Physical changes can be undone. Burning a bit of paper is another non-reversible change.
The temperature of a burning matchstick varies between 71 and 94 degrees Centigrade

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.
Coffee dissolving, water boiling and chocolate melting are reversible physical transformations whereas wood burning is a chemical combustive transformation.
because i said so! thank you for listening, my name is tina!!
A reversible change is where like if you had some ice, you could melt and then change it back to ice again making it a reversible. An irreversible change is something that can't be reversed, like burning food, as you cannot unburn it. Hope I helped!
