Yes. Once it is boiled it cannot be changed back.
No, hard-boiling an egg is a chemical change. By cooking the egg you change its chemical composition.
Boiling an egg is a physical change because it involves a change in the state of matter from liquid to solid without altering the chemical composition of the egg. The proteins in the egg white denature and become solid during the boiling process.
Boiling an egg is and is not a chemical change, depending on how you are chemically defining the egg.Some chemicals inside the egg will undergo various chemical reactions, driven by the heat of the boiling. These reactions will involve the formation of new chemicals with new empirical formulas and the destruction of old ones.Other chemicals, particularly proteins, will undergo changes in their conformation or secondary and tertiary structures. While their empirical formulas will remain unchanged (or largely unchanged), the new structures may have different chemical properties than the old ones.The only way in which the egg does not undergo a chemical change is if you are referring to the empirical formula of the egg as a whole. No atoms leave or enter the egg, so the atomic composition of the egg remains unchanged.
A good chemical change is one that leads to the formation of new substances with different properties from the original substances. This change often involves the breaking and forming of chemical bonds. Examples include combustion, rusting, and digestion.
Chemical. The chemical composition of the egg is changed when the egg is fryed, and cannot be reversed.

Boiling an egg is a physical change because it involves a change in the state of matter from liquid to solid without altering the chemical composition of the egg. The proteins in the egg white denature and become solid during the boiling process.
The egg actually turns solid inside, so that is a physical change. If the egg turned into a liquid or gas after boiling it then that would be considered "chemical change"
protein of the egg is mainly albumin. It is denatured by heating boiling and it becomes solid
Cooking is a chemical process.
Hard boiling an egg involves a physical change. The heat causes the proteins in the egg white and yolk to denature and coagulate, resulting in a solid structure, but the chemical composition of the egg remains the same.

Cooking a hardboiled egg involves denaturation of proteins in the egg white, where heat causes the proteins to unfold and form a new structure. This process is irreversible, making it a chemical change. Additionally, the Maillard reaction between the proteins and sugars in the egg during cooking leads to the distinct color and flavor changes, further indicating a chemical transformation.
