Slow change due the fact that the temperature difference between the egg and boiling water is very high. A fast change is when it occurs almost instantly such as burning paper.
Yes, boiling an egg is a slow change because it involves a physical change in the egg's protein structure due to the application of heat over a period of time. The egg transitions from a liquid to a solid state as it cooks.
No, hard-boiling an egg is a chemical change. By cooking the egg you change its chemical composition.
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"
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.
Chemical change.
protein of the egg is mainly albumin. It is denatured by heating boiling and it becomes solid

Boiling an egg is primarily a chemical change. When an egg is boiled, the heat causes the proteins in the egg white and yolk to denature and coagulate, resulting in a change in texture and structure that cannot be reversed. This transformation alters the egg's chemical composition, making it a chemical change rather than a physical one.
No, boiling doesn't change the shell.
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.
no...there is no way to reverse what you have done to that egg.
