Scrambling an egg is a chemical change. You can tell because chemical changes are irreversible, you cannot change the cooked egg back to a raw egg.
Because you cant re-liquify a solid once it becomes a solid.
it changes the whole appearance and physically changes the substance.
no. its chemical properties do not change, only its apperance.
yes it is a slow change since the egg reacts slowly to give boiled egg.
It is a physical change
Cooking an egg is a chemical change because it cannot be reversed.
Because as it is cooked it goes through a CHEMICAL change, not a physical change.

The parts of the egg (proteins) have become denatured when heated (cooked).
Because it is changing from it's original state and cannot be reversed. That is why you cannot reverse a cooked egg back into its normal state because it is a chemical change (cannot be reversed), but you can change a raw egg into another state.
Both (assuming that they are egg noodles).
yes, a chemical change is anything that cannot be reversed, you cannot uncook an egg! The proteins in the egg are denatured and crosslinked by the heat.

It's still an egg.
Cooked egg white is quite digestible.
