yes, a chemical change is anything that cannot be reversed, you cannot uncook an egg!
Whisking egg whites is a physical change, not a chemical change. Whisking simply incorporates air into the egg whites, changing their texture and volume without altering their chemical composition.
Cooking is a chemical process.
No, hard-boiling an egg is a chemical change. By cooking the egg you change its chemical composition.
Whipping egg whites is a physical change.
During cooking the chemical composition of eggs is changed.
Cooking an egg is a chemical change because it cannot be reversed.
I would say yes
beating an egg is aphysical change because in order to have a chemical change, heat or some other chemical must be involed. so yes, beating an eggis a physical change
Scrambling an egg is considered a physical change because the eggs are still the same substance with the same chemical composition before and after cooking. The proteins in the egg are simply denatured and rearranged through the application of heat, without creating a new substance.

Cooking an egg is a chemical change because the proteins in the egg become denatured through exposure to heat. There is also a physical change because the denaturing of the proteins causes them to become solid at room temperature.
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.
