If you think to a chicken egg - yes, it is an object. But your question is not so clear.
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.
Yes, a raw egg can go through physical changes such as a change in state from liquid to solid when heated to make a boiled egg. This is a reversible change that does not alter the chemical composition of the egg.
Yes, frying an egg is a physical change because the egg undergoes a change in state from liquid to solid due to heat, but its chemical composition remains the same.
no. frying an egg is not physical, because once you turn the egg into a solid, you cant change it back to a liquidish substance. Heating is a chemical change, so there for, frying an egg is a chemical change. Same with baking a cake. Once you add heat to a substance, like cakebatter, you cant change it back into cake batter there for making it a chemical change.
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.
Frying an egg involves both chemical and physical changes. The heat from the pan causes the proteins in the egg white and yolk to denature and coagulate, which is a chemical change. The browning of the egg due to the Maillard reaction is also a chemical change, while the change in state of the egg from liquid to solid is a physical change.
That's correct. Breaking an egge doesn't alter the chemistry of the egg, it just 'breaks' the shell. With a little imagination you could even be able to restore the egg, which isn't possible with a chemical change (such as boiling the egg).
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.
physical
Whipping egg whites is a physical change.
both, because the ingredients are undergoing both physical and chemical changes such as: Butter melting= physical change Egg whites hardening= chemical change both, because the ingredients are undergoing both physical and chemical changes such as: Butter melting= physical change Egg whites hardening= chemical change
