cannot be subjected to shear forces
always expands until it fills any container
has the same shear stress.at a point regardless of its motion
cannot remain at rest under action of any shear force
.
pressure

are viscous
possess surface tension
are compressible
possess all the above properties
resistance to shear stress is small
fluid pressure is zero
linear deformation is small
only normal stresses can exist
incompressible
inviscous
