fluids are capable of flowing

fluids conform to the shape of the con-taining vessels

when in equilibrium, fluids cannot sustain tangential forces

Viscosity of a fluid is that property which determines the amount of its resistance to a shearing force

Viscosity is due primarily to interaction between fluid molecules

Viscosity of liquids decreases with in-crease in temperature

Viscosity of liquids is appreciably affected by change in pressure
