Viscosity is a characteristic of
Options
- Aliquids only
- Bsolids and liquids only
- Csolids only
- Dliquids and gases only
Correct answer
D. liquids and gases only
Step-by-step solution
Viscosity is the property of a fluid by virtue of which an internal frictional force comes into play when the fluid is in motion, opposing the relative motion between its different layers. Since both liquids and gases are classified as fluids and have the ability to flow, viscosity is a characteristic property of both liquids and gases. Solids do not flow, so they do not exhibit viscosity.
