If a cube of jello is cut into two pieces the density of the pieces do not change.
To cut a cube into 504 identical pieces, you would need to make 503 cuts. Each cut divides the cube into two pieces, so the first cut creates 2 pieces, the second cut creates 4 pieces, the third cut creates 8 pieces, and so on. Therefore, to reach 504 pieces, you would need to make 503 cuts.
When a cube is cut by 15 cuts, it can produce a maximum of 27 identical pieces. Each cut can create at most 2 identical pieces, so with 15 cuts, you can get 2 x 15 = 30 pieces. However, 3 of these pieces will be removed as they are the corners of the cube, leaving you with 30 - 3 = 27 identical pieces.
equal the density of any other piece, assuming that the original cube was made of the same uniform substance.

If no cut intersects any previous cuts, then you can just slice it into 14 pieces.
Assuming you mean what property of the two pieces added together changes after the cut is made, it has to be surface area. The total mass of the two pieces remains the same, as does the volume, and obviously color, opacity, and other such properties remain the same, but surface area increases by 2 times the cross section of the cut.
No. Each piece of the cube would have the same density.
no that is a physical property change, not a chemical property.
If you cut a cube of jello in half, it will still have the same total volume. The only thing that will change is the total surface area. Assuming that the piece is a perfect cube, and that it has been divided into two equal pieces, the net surface area of the two resulting cubes would be: Original: SA= 6(h^2) New: SA= 2[2(h^2) + 1/2 (4)(h^2)] Difference: [2(h^2) + 1/2 (4)(h^2)] - 6(h^2) = 8(h^2) - 6(h^2) = 2(h^2) Where: SA = Surface Area h = the length of each side So, if the original cube was 2x2x2 cm, then it's surface area would be 24 cm^2; when it is divided into two, the net surface area of the two pieces together would be 32 cm^2

A physical change in an ice cube can be suggested by observing a change in its shape, size, or phase. For example, if an ice cube melts into water or is crushed into smaller pieces, it indicates a physical change has occurred.

Breaking an ice cube into smaller pieces does not change its identity as ice; it is still made of the same substance, which is water in its solid state. The physical arrangement of the ice cube has changed, but its chemical composition remains the same.

Water would change least in temperature because it has a high specific heat capacity, which means it can absorb and retain heat well without a large change in temperature. Cold Jello, ice cubes, and frozen ice shavings would all change temperature more readily compared to water.
