Detailed Solution

Fluidity is the ability of a liquid to flow, while viscosity is the resistance a liquid offers to flow. Liquids and gases are called fluids because they can flow. However, different fluids flow differently. The property that describes how easily a fluid flows is called fluidity, and the property that resists flow is called viscosity.

Fluidity

Measures how easily a liquid flows.
High fluidity means the liquid flows quickly (e.g., water).
It is the inverse of viscosity.

Viscosity

Measures the resistance to flow.
High viscosity means the liquid is thick and flows slowly (e.g., honey, oil).
Depends on intermolecular forces and temperature.

Aspect	Fluidity	Viscosity
Definition	Ease of flow of liquid	Resistance to flow
Nature	Direct property	Opposite of fluidity
Example	Water (high fluidity)	Honey (high viscosity)
