11. What is the term for resistance to flow? 1. Plasticity 2. Viscosity 3. Fluidity 4. Elasticity

The correct answer is 2. Viscosity.Viscosity is the term used to describe the resistance to flow of a It is a measure of the internal friction of a moving fluid. A fluid with large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because results in very little friction when it is in motion.
