If a tube of jello is cut into two pieces what total property of the new piece change?
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.

If a cube of jello is cut into two pieces what total property of the the new piece change?
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
Is crushing a piece of chalk a chemical change or a physical change?
