Not all physical changes are reversible, but some are.


For example, state of matter is reversible like freezing water turns into ice, unfreeze it will turn back into water even in ice form or liquid form, the chemical formula is still #H_"2"O# regardless of the state of matter.

However, some are irreversible though like using an egg in a cake, it cannot go back to that whole egg again.

the reversible physical changes are reversible bc when a substance changes physically, it is still the same substance, just in a different form.
