usually

For example, if you melt ice, that's a physical change. To undo it, all you have to do is refreeze the water.

Some physical changes may be tougher to undo than others. For example, if you grind glass into a powder, it's possible to melt and reform it into its original size, but it's not very easy.

No, I don't think 'all' physical changes are reversible.

All reversible changes are physical

As they cannot be chemical

But all physical changes are not reversible

Example : When you tear a page. It surely is irreversible but is it chemical?

No. It is not chemical. It is physical change and irreversible change
