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. Permanent change of a matter is also a change of matter which wont regain its previous state. 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.

No. Water freezing into ice is a good example of a "phase change". Ice can melt back into water, so we know that the phase change is not permanent!
