Not all physical changes are reversible because most times when such changes occur parts of the substance is lost to the environment.
That is a chemical change. Physical changes can be undone. Burning a bit of paper is another non-reversible change.

no
No, it is not.
chemical reactions are irreversible but physical changes are reversible
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!
Is a changes which is reversible no new substance is made.
Most cooking processes are chemical reactions. Generally, the reactions are non reversible and once cooked, food cannot be returned to an uncooked state. So, frying potatoes causes a non reversible chemical reaction. The question is not as precise as it might be. Changes can be physical or chemical. They can also be reversible or non reversible but it is important to note that many chemical changes are reversible just as many physical changes are reversible.
freezing is reversible because you can melt whatever it is you froze can't you
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
