 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A fluid’s thickness and resistance to flow is called ____
 A Viscosity B Consistency C Thickness D Magma
Explanation:

Detailed explanation-1: -Viscosity is the resistance of a fluid (liquid or gas) to a change in shape or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow.

Detailed explanation-2: -Viscosity is defined as the resistance to flow! Viscosity is often referred to as the thickness of a fluid. You can think of water (low viscosity) and honey (high viscosity). However, this definition can be confusing when we are looking at fluids with different densities.

Detailed explanation-3: -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.

Detailed explanation-4: -Viscosity is a measure of a fluid’s resistance to flow, a property that affects how it will behave in a pump and in pipework. This can be complex as viscosity can be affected by temperature, pumping speed, pipe dimensions, and, with some fluids, it may also change over time.

Detailed explanation-5: -In layman’s terms, viscosity defines a fluid’s resistance to flow. The higher the viscosity of a liquid, the thicker it is and the greater the resistance to flow. Temperature will affect the viscosity of most materials.
