The density of something is the mass divided by the volume, so if you cut the item in half, it will not change the density at all. Instead, the two halves of the item will have the same density.
Consider what density is. Does it change when you cut the object in half? The object in question will weigh half as much as long as density is uniform. (that is the only hint you should need, if you don't understand go back and do your own homework) If you can't answer this question then some reading wouldn't hurt you. It will only make you less dense!
It depends if you count each half then no. But if you count the whole thing cut in half yes it does change the density.
no the density will be the same
A change in mass would also change the level of density. If the level of mass in an object went down, it would make the object less dense. Anything that is less dense can move faster. Example: Think of someone cutting a pizza in half and keeping one half of it. A half pizza's mass is less than a whole pizza. You can move a half of a pizza easier than you can move a whole pizza, which is how it affects the movement.
An object with lower density than the liquid will float, one with more density will sink. Anything with the same density will stay at the depth where it is placed. If it is placed half submerged it would sink until submerged.
Freezing it should only be a physical (not chemical) change. cutting it in half
The density does not change, as density is the amount of material in a given amount of space. But each piece has the same amount of space and material relative to each other.
The density will be 50 % from the initial value.
No
The density stays the same. The reason why is because the density of something is mass divided by volume, so if you cut the object in half, it will not change at all. :) ((and yes the other answer was gibberish lol.))

No it will not change. Density is mass divided by volume. Since the ratio of the mass is 1/2 and the volume ratio is 1/2, there is no change. The same holds true no matter how you cut the block, as both mass and volume change proportionally the same.
decreases
size does not relate to density
The density does not change.
It's identical. (assuming that the object is homogeneous)
Assuming the object is the same straight through - nothing.
yes
Yes, the density of an object has no relation the number of pieces that the object is divided into, nor to the size of the obect. For example: The density of 1 pound of steel is exactly the same as the density of 1 ton of identical steel, and the density of 1 mL of water is exactly the same as the density of one Liter of water. That is the textbook answer, in real life most cutting techniques disturb the boundary of the cut line. So if you want a real to life answer then the density is only changed at the cut line where temperature and pressure will effect the structure of the metal being cut. Textbook answer is density remains unchanged throughout the whole of the material no matter how many times you cut it. think of density as "how hard something is packed together at the molecular level". This is a ok way to look at density. Cheers!
