That is a chemical change. Physical changes can be undone. Burning a bit of paper is another non-reversible change.
Yes, burning of a sparkle is a chemical change because once sparkle has changed its form it cannot come into its previous form. For understanding you can also take the example of cooked rice which once cooked cannot be raw again.
Both (assuming that they are egg noodles).
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.
When sponge fingers are cooked, they should be a light golden brown color. The texture should be firm on the outside, but soft and spongy on the inside. To ensure they are cooked properly, you can also check for a slight springiness when gently pressed.
A rarer medium refers to a cooking term used to describe meat that is cooked less than medium-rare, meaning it is cooked for a shorter time period and is usually pink and juicy in the center. This term is often used in culinary contexts to describe the doneness of meat.
a physical change is reversible like freezing or melting but a chemical change is irreversible like baking a cake, once it's been cooked, you can't get your cake mix bake
Most cooking processes are chemical reactions. Generally, the reactions are non reversible and once cooked, food cannot be returned to an uncooked state. So, frying potatoes causes a non reversible chemical reaction. The question is not as precise as it might be. Changes can be physical or chemical. They can also be reversible or non reversible but it is important to note that many chemical changes are reversible just as many physical changes are reversible.
no it is not, it is a chemical and irreversible change,
of course its irreversible because once you have cooked the popcorn you cannot turn it back into what it was and originally they were small grains of corn
This is an irreversible change as any cooked food cannot be returned to an uncooked state. This makes it a chemical reaction/change. Hope this helps, Kind regards, sasjade
When scones are cooked what is the change that occurs is 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.
Because as it is cooked it goes through a CHEMICAL change, not a physical change.
it should wiegh less when cooked
As a guess to the meaning of the rather vague question: the main change in food is from the raw state to the state of being cooked.
Meat looks different when it's cooked because:it is no longer rawit is no longer bloodyit has experienced shrinkage during cookingthe color when raw is different than the color after it is cooked
The flavour is different
