The viscosity index refers to the measure of the change of viscosity with a change in temperature.
One of the official definitions for the word viscosity is "the property of resistance to flow in a fluid or semifluid."
Heat decreases viscosity. Lower viscosity means thinner like water. An example of higher viscosity would probably be honey.
Actually we define refractive index with respect to a standard medium. Air has been taken as that standard. Hence refractive index of air is 1 and that of water is 1.33. But refractive index of water with respect to glass is 1.33/1.5 = 0.887 So, the answer is "water".
er...what fluids?
Viscosity is the thickness of a fluid. Example, Petrol would have a low viscosity compared to engine oil. So I would say The Plasma is thicker than normal. It means your blood is thick, look up ways to prevent this.
refractive index is equals to squarroot of relative permitivity
Viscosity is resistance to flow of oil Viscosity Index is a scale to measure viscosity
to calculate viscosity index

One of the official definitions for the word viscosity is "the property of resistance to flow in a fluid or semifluid."
Some properties of solutions are: viscosity, density, refractive index, color, pH, freezing point, etc.
Examples are: density, thermal conductivity, refractive index, viscosity.
