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.
Cooking an egg is a chemical change because it cannot be reversed.
Cooking is a chemical process.
Cooking an egg is both a physical and chemical change. The physical change involves the transformation of the egg from a raw to a cooked state, while the chemical change occurs as proteins in the egg denature and coagulate due to heat. The overall process involves both physical and chemical transformations.
Physical
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.
No, hard-boiling an egg is a chemical change. By cooking the egg you change its chemical composition.

physical change. You know that it is a physical change because it can be reversed. An example of a chemical change would be cooking an egg. Because you cannot reverse the process.
Cracking an egg open is a physical change since the egg and the contents inside do not become a new substance, they remain the same. The shape or the appearance or the physical structure changes that is why it is called as a physical change not chemical because the internal composition is the same.
Getting hotter is physical, getting harder is almost pure chemical.
