Only solids have shape. Liquid takes the shape of the
container which the liquid occupies,. But always the upper
surface of the liquid will be always horizontal
solid is a single state of matter; a state of almost
constant shape and constant volume.
Both shape and volume can be changed if suffient
pressure/stress is applied.
fluid is a group of states; liquid, gas, vapour and plasma;
fluid - - things that flow easily
solids have shape. Liquid takes the shape of the
container which the liquid occupies,.
solid is a single state of matter and constant volume.
Both shape and volume can be changed if applied external
force . fluid is a group of states; liquid, gas, vapour
in solid,the lnter molecular forces are higher so they are
rigid & have definite shape but in fluids these forces are
weak as in gas the particles move in any direction so it
does not have fixed volume.
When force is applied on solid it get deformed and returned
to its original position under its elastic limit.While in a
fluid when force is applied it get deformed and never return
to its original position.
Solids have a definite shape but it can't flow.A solid
resist tensile strength and compressive forces.Examples for
Solids are stone, brick, ice cube etc.
Whereas,
Fluids can flow but it doesn't have its own shape.It resist
no tensile strength but it resist compressive
forces.Examples for Fluids are oil, water, mercury, gas etc.
In fluids, there are loosely spaced molecules,
intermolecular forces are less and when applied to shear
stress it deforms continuously.
On the other hand, solids are having densly spaced
molecules, intermolecular forces are high as compared to
solid and it deforms only after a certain limit which we can
say elastic limit.
what is counter weights.
Why the ship cranes are not having counter weights irrespect
of industrial & civil construction cranes are having counter
weights.
