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

The correct answer is 2. Viscosity.<br /><br />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.
