Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
TRUE OR FALSE:A substance that flows quickly has high viscosity ____
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -false. liquids with high viscosity flow slowly. liquids with low viscosity flow quickly.

Detailed explanation-2: -Fluids with low viscosity have a low resistance and shear easily and the molecules flow quickly; high viscosity fluids move sluggishly and resist deformation.

Detailed explanation-3: -Explanation: Viscosity is a measure of resistance to liquid flow. Thus, a higher value means it has more resistance and thus flows more slowly.

Detailed explanation-4: -Liquids which flow very slowly, like glycerin or honey, have high viscosities. Those like ether or gasoline which flow very readily have low viscosities.

Detailed explanation-5: -Viscosity is a measure of a fluid’s resistance to flow. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion.
