Asmall pebble breaks off of a huge boulder. the pebble has the same density as the boulder in its own words explain how this can be true

Explanation:

When a pebble breaks of from a huge boulder its has the same density as the boulder. Since we know that density is mass to volume ratio so when pebble breaks off from boulder its mass to volume ratio at atomic level remains same. Hence we can say that when a huge rock or crystal breaks into small pieces, density of all (rock and parts) remains same.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
