The viscosity of a liquid is a measure of the difficulty which molecules have passing each other in a fluid. It is dependent upon the size and shape of the molecules and by the magnitude of the cohesive forces and intermolecular bonds such as hydrogen bonding. Spherical molecules have less fl...
Viscosity is a scientific term that describes the resistance to flow of a fluid. The fluid can be a liquid or a gas, but the term is more commonly associated with liquids. As a simple example, syrup has a much higher viscosity than water: more force is required to move a spoon through...

Viscosity is caused by friction within a fluid. It is the result of intermolecular forces between particles within a fluid. These intermolecular forces resist the shearing motion of the fluid and the viscosity of a fluid is directly proportional to the strength of these forces.As a liquid is mo...

What is the effect of temperature on the viscosity of a liquid? What is the difference between viscosity and friction? What is the unit used for thermal conductivity? a) Distinguish between dynamic viscosity and kinematic viscosity. b) What ate their SI units and what is the basis of the IS...
Viscosity.A liquid's ability to flow is one of its fundamental characteristics. However, the degree to which it flows depends on its viscosity, which varies according to its molecular size and intermolecular forces. For example, motor oil has a much higher viscosity than water due to its large...
What is viscosity? The resistance of a fluid to flow is a fundamental concept to understand current viscometer technologies and liquid characterization.
