Question

Which of the following property gives magnitude of friction in molecules of liquid ? a) Density b)Viscosity c)Surface tension d)Vapour pressure

Answer 1

Answer:

b) viscosity

Explanation:

The fluid friction is called viscosity.

Answer 2

The property giving the magnitude of friction in liquid molecules is b) Viscosity

• Friction and viscosity apply to opposing forces.
• Friction is used to refer to forces that resist relative motion while viscosity refers to resistive forces that occur between fluid layers as fluids attempt to flow.
• Viscosity = Force / Per unit area and is directly proportional to rate of shear.
