Fluidity vs. Viscosity — What's the Difference?

A continuous, amorphous substance whose molecules move freely past one another and that has the tendency to assume the shape of its container; a liquid or gas.

The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water.Viscosity can be conceptualized as quantifying the internal frictional force that arises between adjacent layers of fluid that are in relative motion.

Of, relating to, or characteristic of a fluid.

The condition or property of being viscous.

Readily reshaped; pliable.

(Physics) Coefficient of viscosity.

Smooth and flowing; graceful

(uncountable) The state of being viscous.

Changing or tending to change; variable

A quantity expressing the magnitude of internal friction in a fluid, as measured by the force per unit area resisting uniform flow.

Characterized by or allowing social mobility

A tendency to prolong interpersonal encounters.

Convertible into cash

The quality or state of being viscous.

(uncountable) The state of being fluid rather than viscous

A property possessed by a viscous fluid, being a resistance to the forces causing a fluid to flow, caused by interactions between the molecules of the fluid and between the fluid and the walls of the conduit through which it moves; also, a measure of such a property.

(countable) A measure of the extent to which something is fluid. The reciprocal of its viscosity.

Resistance of a liquid to sheer forces (and hence to flow)

The quality of being fluid or free-flowing

The quality of being fluid or capable of flowing; a liquid, aëriform, or gaseous state; - opposed to solidity.

The property of flowing easily
