Question

The property by virtue of which a fluid tries to prevent the relative motion between adjacent layers is called

1. Elasticity
2. Rigidity
3. viscosity
4. cohesion

Answer

viscosity

Explanation

Viscosity is a measure of a fluid’s resistance to flow. It arises due to the cohesive forces between the molecules of the fluid, which cause them to exert a drag force on each other when the fluid is in motion. This drag force leads to internal friction within the fluid, which resists the relative motion between adjacent layers of the fluid.
