For a tube with constant rate of flow, the strength of the compensating force is proportional to the _________.

• Quantity of the liquid

• Friction

• Pressure on the fluid

• Fluids viscosity

Which of these solutions do you think will flow slower?

• Honey

• Water

Which of these factors affects Viscosity?

• Pressure on the liquid

• Temperature

• Friction

• Pressure on the container

Which of these options best suit a highly viscous fluid?

• Low resistance

• Flows faster

• HIgh resistance

• Flows slower

Assertion : The viscosity of liquid increases rapidly with rise of temperature. Reason : Viscosity of a liquid is the property of the liquid by virtue of which it opposes the relative motion amongst its different layers.

• If both assertion and reason are true and the reason is the correct explanation of the assertion.

• If both assertion and reason are true and the reason is not the correct explanation of the assertion.

• If assertion ture but reason is false.
