is breaking an egg a chemical or physical change?
is cooking an egg a chemical or physical change?
Breaking an egg is a physical change. We still have shell (but broken in pieces now) and we still have egg yolk and egg white bit those are now outside th shell.
Cooking an egg is a chemical change. We have changed the chemical composition of the yolk an the egg white.
It is a physical change as because we still have the egg yolk and it's white broken bits which can again be arranged and as the chemical composition of the egg does not change it is a physical change.
