Compare the density of iron in the solid, liquid, and gaseous states.?

Answer 1

When you think of density think of the word condense.
The denser something is the more concentrated the weight at one point, say one cubic inch.

If you have 1 lb of solid iron and 1 lb of liquid iron and 1 lb or gaseous iron then you are going to need increasingly larger containers to hold it.

Solid iron has the molecular movement almost stopped and it is stuck in a crystal lattice. It is condensed as much as it can be; it is denser; there are more molecules of iron per cubic inch.

Liquid iron has its molecules moving faster and that means it requires more space for that molecular movement. The density decreases because at any one spot there is less iron. However the total mass is still one pound. There are fewer iron molecules per cubic inch. The volume has changed, but the weight has not so the density has decreased.

Gaseous iron needs a huge container because the molecules are moving so fast that they need the space to expand and move around in. At any one spot there will be less iron than in the solid or liquid form. Therefore the iron will be less dense in a gaseous form. There will be even less iron per cubic inch than in liquid or solid iron. The volume has increased a lot and so the density has decreased even more.

The forth state of matter is plasma and it is created by heating the material even more. The molecules will need even more space to move around in so a container of 1 lb of plasma iron will be even bigger than the other containers. This iron will be less dense because at any one point there will be less iron molecules than you would have at any other point in the cooler states off matter. Again the density is less because there are fewer molecules of iron per cubic inch. The 1 lb needs a larger container because it has to hold all those fast moving molecules and they need more space to move fast.

Temperature is a measure of molecular movement. The colder it is the slower the molecular movement. The colder it is the more likely a substance is to turn into a liquid or a solid.

Water is one of the very few substances that expands when it cools. This is because the when the water crystals form they use up more space than used by liquid water. In any other case the colder an item is the denser it becomes and the less volume the same weight takes up. Water is one of the few exceptions.

The density of a solid and liquid are almost identical. Liquid iron is probably slightly less dense than solid iron. Gas is much less dense.

Answer 4

ok, lets put it in the simplest way possible... If you drop 1 ton of iron bricks or 1 ton of iron liquid(ignore the temperatures of both) on your foot, which one will hurt your foot more? Now, if you drop 1 ton of iron liquid or 1 ton of iron gas(yeah, really retarded example, but w/e), which one will hurt your foot more? If you need confirmation on the answers brick/solid > liquid > gas. The people above described it more accurately, or scientifically accurate... Density = Mass / Volume, and so on...
