The proteins in an egg are globular (the long chains of amino acids are bunched together, and held that way through weak chemical bonds) and when you heat them, these proteins float around, bumping into water molecules and other proteins. During this process, the bonds break, and reform with other proteins, eventually creating a net of attached protein strings. This net holds in all of the water in the egg. If you cook the egg too long, too many bonds form and the egg becomes rubbery. (credit to exploratum.edu for this info
Eggs contain a myriad of proteins, as well as some fat and carbohydrates. As the proteins are rather complicated, it is not feasible to express them in a chemical equation, rather the proteins in the egg become denatured at high temperatures, changing conformation and interaction with neighboring proteins. The result of heating is that the protein complex becomes white and opaque, and bonded more strongly with each other. Additionally, the evaporation of water from the complex aids with the stiffening of the protein complex in general.
When eggs are cooked they go through a chemical process, a irreversible process.
Eggs have protein molecules, and protein molecules change shape when you heat them. The energy which is given through cooking (kinetic energy for the molecules) breaks some of the chemical bonds (also could be known as an intermolecular bond or a covalent bond) in the protein and this allows the molecules to take a different shape. This gives the food a more edible texture. This change is irreversible. It's called denaturing.
Yes. Cooking an egg is a chemical change. It changes the chemical composition of the egg by denaturing its proteins.
Yes it is
yes i think it change because the color change and that is it.
Due to the higher temperature the very large and not-so-stable protein molecules fall apart and start reacting.
Proteins within the egg denature (change shape)
Scrambling an egg is a chemical change. You can tell because chemical changes are irreversible, you cannot change the cooked egg back to a raw egg.
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.
An Egg is made up mainly proteins.Proteins denaturised when heated above 60 celcius.When cooking an egg it become stiff because of cogulation of proteins
denaturation.
it changes the whole appearance and physically changes the substance.
You cannot uncook n egg
Cooking an egg is a chemical change because it cannot be reversed.
Cooking is a chemical process.
No, hard-boiling an egg is a chemical change. By cooking the egg you change its chemical composition.
I would say yes
yes, a chemical change is anything that cannot be reversed, you cannot uncook an egg!
During cooking the chemical composition of eggs is changed.
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.
Scrambling an egg is a chemical change. You can tell because chemical changes are irreversible, you cannot change the cooked egg back to a raw egg.
explosion of fireworks,cooking an egg
Cooking an egg or burning logs on a fire.
The heat from the cooking denatures the proteins in the egg forming different configurations than in the uncooked egg.
