Beating egg whites to make then stiff it is a physical change. The proteins forming the substance of the egg white are complexly folded molecules and the beating causes them to partially unravel. as they do this they can form a net which can capture tiny pockets of air which increases their volume and makes them appear white. This physical change will partially revert if the beaten whites are left to stand for too long before cooking.
