Detailed explanation-1: -Viscosity is a measure of a fluid’s resistance to flow.

Detailed explanation-2: -Viscosity is defined as the ability of liquid to resist its flow while fluidity refers to the tendency to allow its flow easily. These two terms are opposite in their meaning. A less viscous liquid will have more fluidity and vice versa.

Detailed explanation-3: -Viscosity is a measure of the resistance of a fluid towards being deformed when under shear stress. Hence, it is also known as shear viscosity. It is caused by the attractive forces between molecules in close contact, and the friction between molecular chains.

Detailed explanation-4: -Viscosity is defined as the ability of a substance to resist flow. In a sense, viscosity is the inverse of fluidity. Cold molasses, for example, has a higher viscosity than water because it is less fluid.

Detailed explanation-5: -Viscosity can be not only a fluid’s resistance to flow but also a gas’ resistance to flow, change shape or movement. The opposite of viscosity is fluidity which measures the ease of flow while liquids such as motor oil or honey which are “sluggish” and high in viscosity are known as viscous.
