The property of a fluid that resists relative motion between its layers is called:
A
Viscosity
B
Buoyancy
C
Density
D
Surface tension
Correct Answer: Option A — Viscosity
Explanation:
Viscosity is the internal resistance of a fluid to flow, arising from friction between adjacent layers moving at different velocities; highe...
Viscosity is the internal resistance of a fluid to flow, arising from friction between adjacent layers moving at different velocities; higher viscosity fluids, like honey, flow more slowly than water.
