Because cooking involve chemical reactions, chemical changes, chemical transformations.
Yes, cooking meat involves chemical reactions. When meat is cooked, proteins denature, fats melt, and carbohydrates caramelize, resulting in changes in texture, flavor, and color due to chemical reactions taking place.
because of the smell change and the mass and the density changes
During cooking thermal decomposition of some organic compounds from meat can occur.
because you cant get it to be raw again
yes,
endothermic reaction
Yes. Specifically it involves the Maillard reaction, which is what causes browning.
um
Cooking an onion involves both chemical and physical changes. The heat causes physical changes such as softening and browning of the onion as well as chemical changes such as the breakdown of complex molecules into simpler compounds, resulting in new flavors and aromas.
no it is a physical change because you are just changing the size not the chemical structure
Cooking involve many chemical transformations.
chemical
no
Cooking meat results in a chemical change. Proteins in the meat are long strings of biochemical material, and heat causes them to "unravel" and break down. This is chemical change.
Cooking is a chemical process.
Yes, it is a chemical reaction.
Yes
Cooking involve many chemical reactions.
well the chemical reaction is cooking not physical
both
that's a good question........it depends on if the hot dog is raw or cooked/frozen...............but if the meat is raw and there are bacteria in the hot dog and if you kill it by boiling it then it is a chemical change
Because you are changing the way the original substance was produced. It is a chemical change because you are changing the atoms,molecules and everything that was the original form of the substance.
