Because you cant re-liquify a solid once it becomes a solid.
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.
Well a physical change is when you break something and you still have it like ripping a piece of paper. You still have the paper!! Then you have your chemical change .Which is when you do something to make it to the point were you cant keep it.(EX) Burning a piece of paper in the fire is a chemical change:) Because you cant get it back:)
Cooking an egg is a chemical change because the heat causes the proteins in the egg white and yolk to denature, changing their chemical structure. This irreversible change alters the appearance, texture, and taste of the egg, making it different from its original raw form.
Carving a statue out of marble is a physical change because the marble is simply being reshaped without undergoing a chemical reaction. The composition of the marble remains the same throughout the carving process.
The rotting of leaves is a chemical change because the breakdown of the leaves involves a chemical reaction to decompose the organic matter, resulting in the formation of new substances such as water, carbon dioxide, and various compounds.
Because as it is cooked it goes through a CHEMICAL change, not a physical change.
Yes it is. Because when you cook, you cant get your ingredients back ! =]
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.
well you cant once you have evolved it you cant change it back
you cant once activated you cant change back
you cant
no because its a chemical change nd you cant get it back anyway why did i answer this
because u cant change it back form its original form
you cant change a wolf into a person
Change forst by letting, GO!
I guess it is a chemical change as the exploded fireworks cant be regained back which is possible in a physical change and not in a chemical change.
you cant, once you change it there is not going back
