Chemical. If the component substances are the same at the end of the process, you have a physical change. If your object isn't made of the same substance at the end, it's chemical. Cooking denatures the proteins in the egg.
------------------------------------------------------------------------------------------------------------------------
No the above is incorrect.
It is a physical change. The proteins forming the substance of the egg "denature" above about 60 degrees Celsius. Proteins are complexly folded molecules and the vibration caused by the application of heat causes them to unravel - Once untraveled they tangle up to form a solid and the processes irreversible but because the change is a change in shape it is physical not chemical.
What else can I help you with?
The difference between a physical and a chemical change?
A physical change the chemical compounds remain the same in the change, in a chemical change the chemical compound changes. A good example is if you move a raw egg around in a pan, some of the egg may separate but it's still a raw egg. If you turn on the heat and cook the egg you are chemically changing the egg and it so no longer a raw egg.
Is frying an egg a physical or chemical change?
Frying an egg is a chemical change. A chemical change is when the chemical properties change and when color changes, it is irreversible and obviously, you cannot change a fried egg back to a raw egg. The egg changes color and the substance is not the same.
What if you cooked the egg is it physical or a chemical change?
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.
Is a raw egg to a scrambled egg a physical or chemical change in matter?
yes, it is heated and cannot be changed back to the raw egg by any means.
Could a raw egg have a physical change?
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.
Is frying an egg a physical change?
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.
Is scrambling an egg a physical or chemical 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.
Why cant a cooked egg go back to raw?
Because as it is cooked it goes through a CHEMICAL change, not a physical change.
Is a raw egg cooked a physical or chemical change?
Chemical. If the component substances are the same at the end of the process, you have a physical change. If your object isn't made of the same substance at the end, it's chemical.

When a raw egg is broken is that a physical or chemical change?
it is a physical change because the mass of the egg did not alter and nothing "new" was created. For example, If you squish a marshmallow, it did not change mass, nor create anything new, so it means a physical change. BUT if you roast/burn a marshmallow, the black carbon on the edges was created, therefor, it is a chemical change. hope this helped! science is tough!
Is a cooked egg a chemical change?
yes, a chemical change is anything that cannot be reversed, you cannot uncook an egg! The proteins in the egg are denatured and crosslinked by the heat.
Why is a cooking an egg a chemical change?
Cooking an egg is a chemical change because the heat causes the proteins in the egg white and yolk to denature, changing their chemical structure. This irreversible change alters the appearance, texture, and taste of the egg, making it different from its original raw form.
