Question

what is viscosity? ​

Answer 1

the state of being thick, sticky, and semi-fluid in consistency, due to internal friction.

"cooling the fluid raises its viscosity"

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

plural noun: viscosities

"silicone oils can be obtained with different viscosities"

Answer 2

⭐. The property of resistance to flow is called viscosity.

⭐. Viscositu of a liquid is a measure of its frictional resistance to the flow of liquid .

⭐. If viscosity increases the flow of liquid decreases.

⭐. Liquids which flow raplidly have low internal resistance .

⭐. so their viscosity is less .

⭐. Liquids which flow slowly have internal resistance .

⭐. so their viscosity is high.
