What is anomalous behavior of water?
405810
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/

Depends on conductivity of water which in turn depends on factors such as -- impurities present in water, temperature of water.

It actually can be, believe it or not.  It has to do with hydrogen bonds.  Water exhibits very strong hydrogen bonding due to its polarity, and in order to freeze, these hydrogen bonds in liquid water must be broken.  In hot water, more of these bonds are already broken, so a quick drop in temperature could allow the water to freeze before the hydrogen bonds reform.\n\nNote that this is strictly a kinetic or time-based effect.  Thermodynamics dictates that cold water will freeze faster since a smaller energy drop is required, but in some cases it is entropically favored for hot water to freeze faster.\n\nAlso note that stirring the water vigorously will also break hyrdogen bonds, so stirred cold water will almost always freeze before stirred hot water.  You will only observe the phenomenon of interest when the water is fairly pure and undisturbed, and the temperature drop is rapid enough.\n\nWe discussed this very problem in my graduate-level thermodynamics class.

There are two different "environmental conditions" which would affect the water: very low pressure and very low temperature.\nThe first thing to happen is that the water would "boil" (that is start to turn into a vapor).  This would be described as a "vacuum distillation."  This process (which removes heat from the liquid water), combined with the already low temperature would remove enough heat for the water to freeze.\nIf the container was allowed to remain exposed, the solid water would slowly continue to "sublime" (turn into a vapor under reduced pressure) until some sort of equilibrium was reached.\nNo.  I do not believe that this experiment has been tried, or if tried, the results released to the general public.

after looking around at the usgs fl page for groundwater levels and recent precipitation records, i would guess that your water table has risen somewhat. from what i gather, this is normal fluctuation.  my answer is nothing more than a guess, because the data i looked at doesn't really support any other cause.  (all that just to say "I don't know.)

I think you've got it a little backward.  In molecules like water, there is a permanent imbalance of electron distribution in the molecule.  The oxygen atom in water always has a partial negative charge, and the hydrogens are always partially positively charged.  This is so because the electronegativity of oxygen is very large compared to that of hydrogen.  Therefore, when the two elements form covalent bonds in water, the electrons are pulled more strongly toward the oxygen atom, giving it a negative charge.\n\nBecause of this permanent polarity in the molecule, water molecules are dipoles (molecules with two regions of opposite charge).  When two molecules of water interact, they do so through dipole-dipole interactions.  That is, the positive part of one water molecule interacts with the negative part of a different molecule.\n\nInduced dipole interactions occur between non-polar molecules.  Because of the random movement of electrons in a molecule, just by chance the electron distribution will occasionally be lopsided, giving a slight positive charge to one part of the molecule and a slight negative charge to another part.  If this molecule is close to another non-polar molecule, it's partially charged areas will push the electrons away in an adjacent molecule, inducing a dipole in the second molecule.  \n\nSo, dipole-dipole interactions occur between molecules which are already polar, and induced dipole interactions occur between non-polar molecules, or between polar and non-polar molecules.\n\nCheck out a chemistry book for more details.

Because water is polar and like dissolves like.

Yes there is so please do a simple search on clustered water.I was very interested in this subject which includes(molecular changed water)hexagonal water.If in fact it could deliver what it promised I would have been elated.The truth is it is nothing more than pseudoscience and total waste of your money.I have included a link below that might be a good start for your own consideration of these "quack" products.

It is not air that takes a spherical shape in water but rather the water forces it to take that shape. This is because of surface tension - the same reason why drops of water tend to be shperical. It is the state with least potential energy implying the most stable state.\nIn case of smoke in air, the same thing does not happen as neither air nor smoke does not have any surface tension (being gases, rather mixtures of gases, they are not cohesive unlike water or any liquid for that matter). The simply diffuse into each other randomly (and aided by air currents) however, smoke being a hot mixture of gases, tends to rise higher, hence the wierd upgoing patterns formed by smoke.

Water continues to become more dense as it cools until just above the freezing point.  I can't remember the exact temperature off-hand, but I believe it is very near 33.5 to 34 degrees Fahrenheit.  \n\nBelow that water begins to expand and once it has frozen, its volume increases approximately 10%...that's why ice floats...less dense than the water it came from!  Cool, huh?

MY GOD!  Don't answer if you don't have a clue.\nA) False - water is exactly 1g/cm3\nB) False - ice floats, thus less dense\nC) False - Water is made of two elements (Hydrogen and Oxygen), thus it cannot be an element itself.\nD) True - The mass of water does not change when it is frozen, melted or heated into steam.  It is still H2O.  No atoms were split or made!\nE) False

Water is a very unusual substance. When it becomes a solid and crystallizes. The structure of the ice crystal become less dense and floats. The crystalline structure actually pushes the water molecules away from each other and thus expands. This is very unusual because water is one of the only (if not the only) substance that floats as a solid when it is within its on liquid (if that make any sense). So, in an unconfined area, such as a glass of ice water, you would see that the ice floats and rises above the water. In an confined area, such as a bottle, the Ice has no place to go so it expands the bottle. When you let a little of the ice melt and the is some water in the bottle, the bottle is still under pressure from the ice and the water will come out. To prove this, go ahead and freeze a bottle of water, then let it thaw completely; if there is no ice in the bottle, then the water will not come out. It only come out due to the expansion of the ice.

Water molecules are constantly moving.\n\nWhen water warms up, they move faster and when it boils they move even faster.\n\nWhen water cools down they move slower and when it freezes, they stick together and slow down a whole lot.\n\nHowever, even when water is frozen, the molecules still move around, just much slower than we can observe.\n\nThis is true for all molecules.  At temperature absolute zero, all molecular and atomic movement would theoretically stop.  This temperature has never been achieved.\n\nPS - water molecules tend to be attracted to each other, which is why they stick together when they freeze.  when you pour some water on a table, it will stay together in a "puddle" because the water molecules are attracted to each other.

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.

Good question.\n\nPressure of the trapped gas is supposed to decrease with lowering the temperature.\n\nBut, water increases in volume as its temperature is increased below 4 degree C. In other words, water has the maximum density at 4 degree C. Increasing or decreasing its temperature from that point will make it expand.

Water molecules attract each other. This is called cohesion. \nThe oxygen end of water has a negative charge and the hydrogen end has a positive charge. The hydrogens of one water molecule are attracted to the oxygen from other water molecules. This attractive force is what gives water its cohesive properties.\n\nSurface tension is the name we give to the cohesion of water molecules at the surface of a body of water. It is the reasons that water contracts in drops.\nWhat is happening? Each molecule in the water drop is attracted to the other water molecules in the drop. This causes the water to pull itself into a shape with the smallest amount of surface area, a sphere. All the water molecules on the surface of the bead are 'holding' each other together or creating surface tension.\n\nSurface tension allows water striders to 'skate' across the top of a pond. You can experiment with surface tension. Try floating a pin or a paperclip on the top if a glass of water. A metal pin or paper clip is heavier than water, but because of the surface tension the water is able to hold up the metal.
