The resistance of a fluid to flow is known as

• Pressure

• Density

• Viscosity

• Surface tension

Surface tension is a property of

• Solid objects

• Capillarity

The density of a fluid is defined as its (a)   per unit volume.

A fluid's (a)   is the force per unit length exerted along its surface when exposed to air.

Fluids that exhibit a linear relationship between shear stress and shear rate are known as (a)   fluids.

The unit of pressure commonly used in SI is

(a)  

The device used to measure atmospheric pressure is called a (a)   .
