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

flow

shape

volume

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

viscous and incompressible
