I'll give a medal if someone can help me :) Explain how objects can have the same volume, but different masses. What term do we use to describe this relationship?

it wont let me open thee page :/
I'll type what is says...
ok :)
If they have different densities. Imagine a balloon. Now fill it up with air: it expands. Imagine another balloon, and fill it with water until it has the same volume as the first one. The water filled one will be much heavier. This is because the water particles are much closer together; you can fit more of them in the same volume. The gas particles, on the other hand, bounce around with lots of empty space in between them. There are fewer gas particles and the balloon has less mass.
Take one brand new golf ball. It has a mass, it has a volume, and (mass) / (volume) is the density of the golf ball. Now take a carton of 24 of the same identical golf balls. The whole load of them has 24 times as much mass as the single ball, and it also has 24 times as much volume as the single ball. When you divide the total mass by the total volume you get exactly the same number you got for the single ball. 24 of them all together have the same density as one of them has, even though their mass is different from a single ball and their volume is different too. The density doesn't depend on the mass or the volume. It only depends on the answer to the division of one by the other. That's why it's such a useful number. It totally does not depend on the size of the sample. The density of golf balls can be directly and precisely compared to the density of dust particles, boulders, battleships, and asteroids.
