Cooking involve chemical reactions.
Cooking a potato is a physical change because it undergoes a change in form or appearance, but its chemical composition remains the same. Cooking causes the potato's starches to gelatinize and its proteins to denature, but no new substances are formed.
Heat causes the breakdown of starches (long chain carbohydrates) into simpler to digest sugars (mono and dimer carbohydrates). This involves breaking chemical bonds, so it is a chemical change.
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.
cooking an apple is causing a physical change because in a physical change, the IDENTITY of the substance never changes. (identity=atomic makeup. in a chemical change, the IDENTITY does change, due to a chemical reaction. because there is no change in the identity of the apple, baking it is a physical change
It is as irreversible change, so it is chemical.
Cooking oatmeal is a chemical change.
yes, cooking is a physical change. Mostly stuff that are cooked are chemical changes
Cooking is a chemical transformation.
Physical
Cooking is a chemical process.
no,it is chemical change
Cooking is a chemical process.
Physical change :D
It is as irreversible change, so it is chemical.
Basically it is an Chemical reaction due to that it change it physically too. It is a chemical.
Its physical because the chemical properities of it doesn't change.
Cooking involve chemical changes.
