Sand Is Liquid..

 



  From the child-hood teachers and peoples say that sand is solid. They also say that a liquid is that state of matter which has fixed volume but variable shape.


  This is very confusing facts for me, that how can anything which has fixed volume and varying shape can be solid. Not only for sand they also tells the same for salt, sugar and all other these kind of material.


  I am still searching for a standard ans for this question. But for a logical thought one can easy prove that sand is more like liquid than solids. The properties of liquid are as follows:


1. Liquids have definite volume.
2. Liquids don't have definite shape, they acquire shape of vessel.
3. Liquids flow from higher potential to lower potential.
4. Liquids are incompressible.
5. Liquids have buoyancy.
6. Liquids have viscosity.
7. Liquids have surface tension.
8. Liquids have boiling point.
9. Liquids don't have a lattice of atoms.
10. Their bonding energy is less than solids but higher than gas.


Now fit these things to sand:
1. sand have definite volume, one can't change volume of sand at a constant temp. without adding or removing sand from the sample.
2. sand acquire shape of vessel in which it is placed, and it have spherical shape in free space like all liquids.
3. sand flows from higher potential level to lower.
4. sand is incompressible at normal temp.
5. sand have buoyancy, any thing will dip into sand if it has enough density to do this, sand have very high buoyancy.
6. sand have viscosity it will tear apart when it intended to flow due to low particle bonding, low viscosity and low elasticity.
7. Due to lower bonding energy of gravity sand have very thin outer surface, one can see the outer film over a sand if it is in very huge amount.
8. sand have boiling point at bout 3,675°C. {People say it sublime at that temp}.
9. sand don't have a perfect arrangement of particles which make sand as sand, but a single pebble may have such arrangements.
10. When it comes to sand the bonding energy is of gravitation energy and it's value is always less than solids and greater than gasses.


All the fact are in favour that sand is liquid.


When I represent sand as liquid to the peoples they say "Okay that's all right but we can see particles of sand, but not of water, and although there is not present a lattice between particles of sands but each pebble have a definite lattice ?"


But they forgot both thing before saying that visibility is not a criteria of stats of matter. Just because we can see the particles of sand it is solid and of water not it is liquid, this is just not fare.


And what about lattice ? Lattice is basically an arrangement of atoms or molecules, in the case of sand pebbles have lattice so it is solid, now what about the Benzene ? The benzene also have lattice structure between the particles.


Another thing come into mind that all particle of sand are not in similar size and shape but they vary in different manner. If that is a reason behind sand is solid then what about petroleum and petroleum products, all the petroleum product have variety of molecule arrangement, size and shape.


The above discussion is true not only for sand alone but for all the material like sand for example : Salt and sugar.


Now it is clear that sand is liquid.......
