Cooking an egg is a chemical change because it cannot be reversed.
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.
Because as it is cooked it goes through a CHEMICAL change, not a physical change.
Both (assuming that they are egg noodles).
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.
When scones are cooked what is the change that occurs is a chemical 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.
Yes, cooked rice is an example of a physical change. This is because the rice undergoes a change in form, texture, and appearance when it is cooked, but the chemical composition of the rice remains the same.
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.
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).
When an egg is cooked, the proteins in the egg white and yolk denature and coagulate, resulting in a solid structure. The texture changes from raw and slippery to firm and cooked, with the egg white becoming opaque and the yolk changing from runny to solid, depending on the cooking time.
Cracking an egg is a physical change, not a chemical change.
