It is a physical change.
No, the process of jello setting involves a physical change rather than a chemical one. When the jello mixture cools in the refrigerator, the gelatin molecules bond together to form a semi-solid structure, but the chemical composition of the jello powder remains the same.
No, shaping of steel is a physical change, not a chemical change. The steel's chemical composition remains the same before and after shaping, only its physical properties, such as shape and size, are altered.
This is a trick question because you cant answer it without knowing more. 1. if you mean how Gelatin is made, you take animal hoofs, hides, and intestines and then clean them and boil them and process them into mushy slop. Then you take that and let it dry out and then grind it into small dust. Then add some flavoring and stick it in a Jello box for people to eat. This process is a chemical process to change the animal parts into Jello. 2. If you mean when you mix a box of Jello in some hot water then let it sit in the refrigerator, then it is a physical change from powder to liquid to a wiggly solid.

Very close to Jello. It doesn't expand when setting up, and is made of water and a bit of powdered Gelatin and flavoring.
Jello(tm) is not a chemical element and therefore does not have any valid atomic mass.
The process of making Jello is an exothermic change because energy is released in the form of heat as the gelatin sets and solidifies.
If a cube of jello is cut into two pieces the density of the pieces do not change.
it hasn't
