Which type of viscosity measures fluid resistance to flow under the influence of gravity?
Detailed Solution for Test: Viscosity - Question 5
Kinematic viscosity measures fluid resistance under gravity, providing insights into fluid behavior distinct from dynamic viscosity.
Test: Viscosity - Question 6
Save
What is a common example of a non-Newtonian fluid?
Detailed Solution for Test: Viscosity - Question 6
Honey is a practical example of a non-Newtonian fluid, displaying variable viscosity under different conditions.
Test: Viscosity - Question 7
Save
What instrument is commonly used for accurate viscosity measurements?
Detailed Solution for Test: Viscosity - Question 7
A viscometer is commonly used for precise viscosity measurements, offering accurate insights into fluid characteristics.
Test: Viscosity - Question 8
Save
What factor influences the viscosity of liquids at a rapid rate?
Detailed Solution for Test: Viscosity - Question 8
The viscosity of liquids decreases rapidly with an increase in temperature, promoting easier flow.
Test: Viscosity - Question 9
Save
In the U-tube viscometer, what does the time taken for the liquid to pass between marks indicate?
Detailed Solution for Test: Viscosity - Question 9
The time taken for the liquid to pass between marks in the U-tube viscometer is proportional to kinematic viscosity.
Test: Viscosity - Question 10
Save
Which fluid demonstrates substantial resistance to motion due to robust intermolecular forces?
Detailed Solution for Test: Viscosity - Question 10
Honey, due to its robust intermolecular forces, demonstrates substantial resistance to motion, resulting in high viscosity.
