which is the 4th state of matter?? other than solid liquid and gas?

Plasma - fire is considered to be an example of a substance in this state.

Suprise answer and correct! PLASMA\nPlasma is also the most common form of matter in the universe!

No one knows exactly.  It's interchangeable with matter, but no one knows exactly what matter is either.  We can describe properties of matter and energy with reference to each other, but we can't really objectively understand what they are.

Other substances that have a solid less dense than their liquid include the elements bismuth, gallium, and germanium.  Bismuth has a liquid density of 10.05g/cm^3, and a solid density of only 9.78g/cm^3.  Gallium has a liquid density of 6.095g/cm^3, but a solid density of 5.91g/cm^3.  Finally, germanium has a liquid density of 5.60g/cm^3 and a solid density of 5.323g/cm^3.\n\nJust for comparison, water has a liquid density of about 1.0g/cm^3 and a solid density of 0.917g/cm^3.\n\nI think I have heard of other materials that also posses this unusual property, but I can't remember them off the top of my head.  I hope this has been helpful.

helium,.........,hydrogen,............, and oxygen??? I don't have the book on me right now, so I am drawing a blnk

Hey check this out, I guess there are 7 states.\n\nThese phases include gases, plasmas, liquids, fluids, superfluids, solids, and Bose-Einstein condensates.\n\nSorry about all the rephrasing.

The first part is correct.  If the numbers in the second part are correct, it is true only for an ideal gas.  Other materials have various densities in their liquid and solid states.

I remember this question since it was on the test once:\n\nList the following kinds of matter by how well they conduct heat (from the best to the worst): Wood; air; metal; water.\n\nMy answer was the correct one and it was: Metal; water; wood; air.

Perhaps the asker does mean phase. (The distinction is: "Phases are sometimes called states of matter, but this term can lead to confusion with thermodynamic states. For example, two gases maintained at different pressures are in different thermodynamic states, but the same "state of matter". -wiki)\nWhen a substance changes from the solid to the liquid phase, the separation between the particles (atoms or molecules) increases. It takes energy to make this increase because of interatomic/intermolecular attraction. The energy is supplied as heat removed from the environment. This heat is called the latent heat of fusion.\nThe same argument applies to a phase change from liquid to gas. Particles are still more separated in a gas. The heat required to accomplish this is called the latent heat of vaporization. See the ref. for a more complete explanation.

All three states (solid, liquid and vapor) exist at the triple point. Typically, for each one-component substance, there exists only one triple point -- a unique temperature and pressure. Helium is the exception, it will not freeze under its own vapor pressure.

Of the SAME substance or different ones?\n\nAnd in what context?\n\n\nliquid, plasma, gas, solid, gel, sponge, degenerate gas, supercritical fluid.

Say goodbye to matter, I suppose.\n\nWithout electrons (which are negative), all chemical bonds would collapse - so definitley say goodbye to any and all compounds. There goes most materials.  Ditto for chemistry.
