Is printing a reversible change? Why?
No. It's a chemical change because the process is irreversible, there is a change in colour and a change in odour.
A reversible change is a change you can make, then put back, however a non-reversible change is a change you can make, then it will be stuck like that
physical change is reversible because you can undo it for example: if you fold a paper you unfold the paper. chemical chang is irreversible because if you make somthing together you could not seperate them.
Irreversible
Surface rusting may be removed without weakening the metal nail too much. A badly rusted nail may not have enough metal left to be strong enough to still be useful. Therefore, irreversible change depends on the depth the rusting has reached.
Cutting down a tree. shredding of paper as well as same of the irreversible change
Yes.
irreversible change
An irreversible change is a process that cannot be undone or reversed. Once the change occurs, it is permanent and cannot be restored to its original state. An example of an irreversible change is burning a piece of paper: once the paper is burnt, it cannot be turned back into its original form.
A potato that has melted cannot look like what it was again.

irreversible change.
irreversible change is called a physical change.
Burning something is irreversible.
Yes, but it is so hard as not to be worth it.
Do you mean irreversible change? If so it means "It can not be changed".
Most changes in hand soap are reversible, meaning it can go back to its original state. For example, if a solid bar of soap melts when heated, it can solidify again when cooled. However, if the soap is burned (irreversible change), it cannot return to its original form.
