it changes the whole appearance and physically changes the substance.
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.
Cooking the eggs is a chemical change because the heat alters the molecular structure of the egg proteins, causing them to denature and coagulate. Adding milk to the eggs is a physical change because the milk remains unchanged in composition and simply mixes with the eggs.
Physical
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.
You know a chemical change happened if: -A change in color -Formation of a precipate (a solid) -Formation of a gas
Cooking is a chemical process.
No, hard-boiling an egg is a chemical change. By cooking the egg you change its chemical composition.
During cooking the chemical composition of eggs is changed.
yes, a chemical change is anything that cannot be reversed, you cannot uncook an egg!
Cooking an egg is a chemical change because it cannot be reversed.
I would say yes
explosion of fireworks,cooking an egg
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.
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.
Egg goes from liquid to solid. Water becomes steam, pan becomes hot. Cooking = chemical change.
Cooking an egg or burning logs on a fire.
Cooking an egg is a chemical reaction because of how the proteins of the egg change through the heating process. The heating of the egg white, for example, converts the amino acids to a different protein arrangement that is of bound texture.
