Burning is an irreversible change.
Burning toast is not reversible. Once the toast is burned, the chemical composition of the bread changes due to the high heat, leading to the formation of new substances like carbon. While you can scrape off some of the charred parts, you cannot return the toast to its original state.
That is a chemical change. Physical changes can be undone. Burning a bit of paper is another non-reversible 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
This would be a irreversible change. If you think about it, if you let the bread sit after being toasted it will not become un-toasted. It may become mushy after time but once you toast it its toast.
Burning is an irreversible change.
Yes, this change is reversible.
This is a reversible process.
You think probable to a reversible reaction.
The difference between reversible and irreversible is that reversible changes can be changed and irreversible changes cannot. Apart from sometimes but it usually is really hard. Also when the change is reversible no new substances are formed. When the changes are irreversible they are. Something that is reversible can be changed, something that is irreversible cannot be changed. For example, bread into toast is an irreversible reaction, because you cannot turn the toast back into bread.
reversible
no soil is not reversible.
reversible!
