What is a permanent change?
In science change is nothing but the transfer of a matter or mixtures of matters from one state to another. Here the physical 'state' is not a matter, it may change or not.

Burned paper is an example for permanent change and vapourisation of water is a temporary change. we can classify the changes(either physical or chemical) according to the changes whether it is permanent or temporary.
