What evidence supports the claim that the density of a full piece of clay is the same as it is for a piece of clay that came from the original?

What scientific reasoning explains why a piece of clay does not change density if it is broken in half?

Why can you use density to identify a substance?

If you were able to compress the clay and the particles moved closer together, how would that affect the density of the clay?

If a gold bar has a density of 19.3 g/cm3, what is the density of a gold bar that is half the size of the original one?

(a)   has a mass of 8g and a volume of 4cm³

A student measured the mass and volume of a small cube made of an unknown metal. The mass of the cube is 25.0 g, and the volume of the cube is 3.19 cm³. The student is told that the cube is a sample of one of the four metals listed in the table. Based on the data, the unknown metal is most likely ​ (a)  

"The balls have the same ​ (a)   , but the foam ball has more ​ (b)   .

So, the ​ (c)   has more density.
