How can particles be used to explain all that we have learned about density?
Some specifics:
-the density of water is 1 g/ml no matter how much water there is.
-the density of the same kind of metal is the same no matter how much metal there is.
-When adding salt to water, the density goes up.
-things that are less dense than water float.
Again, how can particles explain all of those things and more?

Particles are more spread out in the objects that can float. The objects that can't float are more compact and the paricles are closer together.

and with the salt there are salt particles as well as the original water particles

How does adding salt particles increase the density? I think this needs to be explained further to be clear.

Wouldn't it add to the mass?

the salt dont make the water rise alot bc like u can hardly see it when u do that

Salt particles increase the density by adding more mass which increases the density.

[glow=red,2,300][glow=red,2,300]the density is different when you put salt in it because you put more mass giving a bigger number to divide.[/glow][/glow]

So if you put salt in water there is more density

So if you put salt in water there is more density Yes but how is there more denstiy explain further so we can all understand ok |

When you put salt into water you would also be adding to the volume. If you watch when you put ice or anything in water it rises up. So not only would you be adding to mass, you would be adding to volume.
