Actually, you can use many other materials for a thermometer, not just mercury.   Mercury is nice because it has properties that make it easier to build a more practical thermometer than the others.   For one it is liquid at room temperature.    Mercury would not be a good material for a thermometer below it's freezing point (see www.webelements.com for details)    Assuming we want thermometer for measuring temperature variations around room temperature, then the other properties of mercury, that is, its temperature expansion coefficient and pressure compressibility, are just right so it will expand predictably over the approximately 1 or 2 inch range that it in your thermometer.    \n\nHope that wasn't too long winded.

the question as written has no answer.  hydronium is an ion that only exists in a solution, never by itself. so it can't have a melting point or freezing point or a density

Mercury\n\nA heavy, silvery, transition metal, mercury is one of five elements that are liquid at or near standard room temperature (the others are the metals caesium, francium, and gallium, and the nonmetal bromine)

mercury is the heaviest medal/ water is hydrogen and oxygen

francium. mercury is technicaly not a metal, it just has a low melting point, low metling points do not make it unstable. if that were the case, then oxygen would be VERY unstable ITS ALREADY TURNED INTO VAPOR!!!

Could you try the old idea of different types of liquid in a clear glass/plastic tube. Each has a different density, so the heaviest goes to the bottom, the lightest to the top? Cant remember the exact liquids to use, but something dense like oil, then baby oil, water, etc.....the tube can be shaken, but the liquids will always seperate out in layers......

the density of water is 1 gm/cc.however the density of ice is less than 1gm/cc.this means that d density of water of water increases when it changes to ice.this is known as anomalous expansion of water.

Osmium and Iridium are the two most dense elements in pure form. They are also very pretty metals, iridium particularly. Unlike osmium, iridium does not tarnish in air, and is in fact impervious to many forms of chemical attack, much like platinum. An alloy of 90% platinum and 10% iridium is widely used in both the jewelry and chemical industries, because it is strong, hard, beautiful, and impervious to almost all chemicals even at very high temperatures.\n\nWhich is the most dense element, osmium or iridium? That honor has changed hands a couple of times over the years.

The terms are similar, but they do differ.\n\nDensity, as usually expressed, is in grams/cubic centimeter-----for example, the element mercury has a density of 13.6 grams per cubic centimeter.Density is non-variable.\n\nSpecific Gravity is a way of relating weights of substances to the weight of water. Therefore, specific gravity, as we measure it, is really specific gravity in the earth's gravitational field at sea level at 0 degrees C.

look at column 7.  all of the densities appear there in grams/cm3.\n\nhttp://www.science.co.il/PTelements.asp

Transition metals are stable.  Mercury is a metallic liquid at room temperature.  Diamond and graphite are allotropes of carbon.  H, N, O, F, Cl, Br, I, At form diatomic molecules.  He, Ne,Ar, Kr, Xe, Rn are monoatomic gases at room temp.

The simple answer is solid, liquid and gaseous, the same as all other materials. However, if one wants to probe a bit deeper:\n\n1. One can imagine that if the water were subjected to extreme conditions, that it could form a plasma, the fourth state of matter. \n\n2. There are many forms of the solid version of water, ice:\n\na. the simplest crystalline phase of ice is hexagonal, also known as Ih\n\nb. under different conditions, other crystalline phases exist, known as II, III, V, VI, VII, VIII, IX and X. \n\nc. ice can also exist in amorphous states, amorphous solid water (ASW), low density amorphous ice (LDA), high density amorphous ice (HDA), very high density amorphous ice (VHDA) and hyperquenched glassy water (HGW).\n\nd. ice can also form a clathrate hydrate, in which gas molecules are trapped in an ice crystal lattice (deep on the ocean floor, on the outer planets in the solar system possibly, inside arctic gas pipelines).\n\nAnd these are just the ones we have found so far. Depending on what you call a "phase", there are many, many phases of water.

The CRC Handbook of Chemistry and Physics has all kinds of good information like that (although it is pricey).\n\nOr, search the web for the specific liquid of interest.

To determine density you also have to know the temperature.  The colder a substance gets, the more dense it becomes (ie. the particles come closer together).  Water is the one odd ball, it becomes most dense at 4 degree C instead of below freezing like most substances.

Mercury\nIts liquid at room temperature so it has to be.
