Water has several unique properties. Which one of these isn't one?

D) It's heat of fusion is higher than its heat of vaporization.\n\nWater's heat of fusion is: 334.5 kJ/kg\nWater's heat of vaporization is: 2256 kJ/kg\n\n\nE IS NOT CORRECT BECAUSE: Water is denser than ice. If water was not denser than ice, ice would not float.\n\nAnd Mr. the_bendude, you must have never taken chemistry. Heat is not the same as temperature. Yes, water boils at 100C and freezes at 0C, but that does not mean those are the heats for which it does.

That is definitely not correct!!\n\nFor example water (H20) is very very different from the two gases that make it namely hydrogen (H2) and oxygen (O2)

We can use water (H2O) to explain the difference between a compound and a molecule.\n\nWater, if you look at it on a macro level, is a COMPOUND, and this compound consists of many many (_illions) of water MOLECULEs (at the micro level) 'clumped' together. \n\nTo illustrate, take x to be a molecule of water. The box would represent the compound water.\n\n --------\n| xxxxx|\n --------

The problem with this question, is that there are more than 3 states of water. \n\nThe classical states of water are ice (solid), liquid water (liquid) and water vapor (gas). \n\nA state is also known as a phase, and the transition from one state to another is called a phase change. The transition from liquid to gas is called evaporation, and the transition back is called condensation. The transition from solid to gas is called sublimation. The transition from solid to liquid is called melting and the transition back is called freezing. \n\nHowever there are other phases of water, or states, as well. If you apply enough energy, you will get a plasma.Under different ocnditions you will get different forms of ice such as ice II, III, V, VI, VII, VIII, IX, X, XI,  and XII. As well as crystalline forms solid water can exist in amorphous states as 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). One can even get gas molecules trapped inside water cages, called clathrate hydrates.

I am not an expert, but I am on my local watershed watch team. We conduct water samples and look for species diversity in the water. Factors that affect diversity in water is the clarity, amount of sedimentation/other pollutants, temperature, stream bottom material (sand, mud, rock, etc.),sinuosity, percentage of dissolved oxygen, turbidity, and vegetation surrounding the stream banks. Also I would think diversity depends on the location of the river. There will obviously be differences in a river that runs near Chicago and a river that runs through the Adirondak Mountains. I am sure I have left many things out, but hopefully i've said a few things you could do a search on.

The difference in solubility of the components allows for separation.  I don't remember the specifics, but that is the reason.  Water will not have a big enough difference.

Water has a special property, called Anamolous behaviour of water, and this property is seen only in water.\nWater's melting point is 0 degree Celsius, and you might think that the volume increases if further heated above 0 degree celsius, and you are wrong ! Only in water, the volume of water decreases until it is heated to 4 degree celsius, and then it starts increasing, unlike any other liquid (in other liquids, replace 0 degree by their melting point). Therefore, volume of water is least at 4 degree celsius and not at 0 degree celsius. This property of water is called Anamolous Property of water or Anamolous Expansion of water.\n\n--\nWWW - Weird & Wonderful Web - http://www.kudige.blogspot.com/

water itself, of course.\nThe following ions.....\niron ions, calcium ions, sodium ions, chloride ions, fluoride ions...\n\noxygen molecules, carbon dioxide molecules, sometimes around here hydrogen sulfide molecules.\n\nALMOST EVERYTHING is in water in minute concentrations.

The density is different - sea water being more dense than fresh.\n\nFreezing point (lower for sea water) and boiling point (higher for sea water) would be slightly different.\n\nElectrical conductivity would be different (higher for sea water).\n\nAll these things are different - but the differences are also all due to the salinity difference that you mentioned.

water. it's the creator of life.

water is Di pole material which means that it has some polarity due to partial charge distribution between oxygen and hydrogen . \n\nsince it is a di pole , it is divided into ions as \n\nH2O = OH-   + H+\n\nor it accepts an H+ and becomes  H20 + H+   = H3O+  \n\nso it seems like ions are the main thing to carry electrical current . so water can curry current providing a power source \n\n\nPURE WATER CANNOT HOWEVER CARRY ELECTRICAL CURRENT

i agree with the second one.  water is clearly defined as having two hydrogen and one oxygen atom.  if it doesn't have oxygen, then it can't be water.\n\nit is possible that the "water" is actually liquid hydrogen, carbon dioxide, etc.  if the "water" is a solid, it can be the frozen of anything above plus lots of other compounds or elements.\n\nif this meteorite was found on earth, then it probably wasn't any of those either since it would have melted.  if it was still a meteor in space, then it could be.  comets are known to have "ice" and dust as their tail.  this isn't really ice as in water turned to ice, but ice is used to refer to other elements or compounds in the solid form (dry ice is CO2).\n\nif you read that in an article in a magazine or newspaper, they were probably try to make it easier to understand what they were trying to say, and decided to use water to describe a liquid or ice to describe the solid that they found.

Fresh water evaporates faster than the solutions will.  Between the solutions it would depend on the number of particles dissolved in the water.

It's a completely different chemical once combined with Hydrogen in the form of water.  It's going to have a completely different set of properties.

the water, earth and moon are always moving......why is some water clear and some murky?  there are so many factors, bacteria in water don't live in warm water, so in tropical places the water is clear, on the other hand, places like east or west coast usa are colder so the water has a higher degree of pollution or looks more "murky"

water is H20 ( 2 hydrogen and 1 oxygen atoms). The Hydrogen atom's electron chemistry dictate it to be positive, where the oxygen atom's electron chemistry dictate it to be negative, so the negativity of 1 water atom will non-covalently bind to the positivity of ANOTHER water atom, and so on. So overall, H2O molecules form a lot of weak bonds that hold them closely, and it will take a lot of energy to break those bonds and let water be vapor. So it take a lot of heat energy to boil water/break water bonds.
