First of all, you have to break it apart. What is Viscosity?=thickness, stickyness, how it moves. To measure the thickness, you can either slide something down a slanted platform, or drop a marble into each jar of the liquids that you are comparing. To measure the stickyness, it would be a good idea to put cardboard on the two sides of the liquid, and stretch them apart, and see what happenes. Lastly, to measure how it moves: try and poor the liquids you are trying to compare down a slanted platform, and see how it moves.
There isn't really something that can measure exact levels of viscosity.
In conclusion, you can't get exact measurements of viscosity, but you are able to find out which liquid has the most viscosity, and which one has the less.
Viscosity is the measure of fluidity a liquid exhibits - meaning how thick or how thin it is.
Viscosity of liquid newtonian substances can be measured by measuring the time a liquid moves in a graduated tube from Point A to Point B at a given temperature usually 20oC
Collodial substances can be measured using a graduated cup. The time taken for the liquid to drain out of the cup. the end time taken when the liquid stream breaks.
In dilute solutions, an Ubhellode Tube is used. Here again, the time taken for a volume of liquid to pass from Point A to Boint B.
In polymer melts, viscosity (melt viscosity) is done by measuring the torque of a synchronised stirrer in the molten polymer at a certain temperature. Example by using the Broofield Melt Indexer

consider two layers of fluid from a fixed layer. Then according to Newtons Law of viscosity, the viscous force(F) acting tangentially is directly proportional to the area of the layer(A) and is also directly proportional to dv/dx.
F directly proportional to A..................(1)
F directly proportional to dv/dx...................(2)
therefore from (1) and (2)
F directly proportional to Adv/dx
removing proportionality sign, we get
F=coefficient of viscosity multiplied by Adv/dx
hence,
coefficient of viscosity =Fdx/Adv
In general, in any flow, layers move at different velocities and the fluid's viscosity arises from the shear stress between the layers that ultimately opposes any applied force.
Isaac newton postulated that, for straight, parallel and uniform flow, the shear stress, τ, between layers is proportional to the velocity gradient, ∂u /∂y, in the direction perpendicular to the layers.
Here, the constant μ is known as the coefficient of viscosity, the viscosity, the dynamic viscosity, or the Newtonian viscosity.
This is a constitutive equation (like Hooke's law, Fick's law, Ohm's law). This means: it is not a fundamental law of nature, but a reasonable first approximation that holds in some materials and fails in others. Many fluids, such as water and most gases, satisfy Newton's criterion and are known as Newtonian fluids. Non-Newtonian fluids exhibit a more complicated relationship between shear stress and velocity gradient than simple linearity.
From Wikipedia:
Viscosity coefficients can be defined in two ways:
Dynamic viscosity, also absolute viscosity, the more usual one (typical units Pa·s, Poise, cP);
Kinematic viscosity is the dynamic viscosity divided by the density (typical units m2/s, Stokes, cSt).
Viscosity is the state of a material when it is thick and sticky and does not flow easily.
BY viscous flow through a capillary tube or by Stoke's method.
The viscosity of materials is not calculated but measured with some instruments, especially viscosimeters.

Density is just one aspect to the physical properties of a liquid if the liquid is very dense, less dense materials can float on it and denser materials will sink into it for example, salt, a moderately dense mineral, can float on mercury, a very dense liquid at room temperature. Viscosity is the next aspect to liquids and probably the word you were looking for when the question was asked. A high-viscosity liquid is very thick. Gelatin is a very Viscous liquid; Water, a not-so-viscous liquid. high-viscosity liquids slow down the movement of objects inside of them. hence why Grandma can make Fruit suspend inside of Jello. Chemical properties are the third aspect. if you put pure potassium inside of water, the water would react and make a fireball. (however it is ill-advised to do so unless you are experienced with chemicals
Liquid is one of the 3 (or 4) states of matter: Gas, liquid, and solid. Being a liquid really has nothing to do with its conductivity. Example: Pure water is not a good conductor. Pure mercury in liquid form is a really good conductor. The Fourth state of matter is considered to be Plasma.
This is dependent on the amount of particles in the liquid. Dirty or Salt water is a conductor but not as effective as other materials. If the liquid contains minimal particles, for example pure water, it is considered a poor conductor and consequently a good insulator.
Yes, light is a form of pure energy as it has no mass. Similar to things like thunder and fire, light is none of the three phases of matter: solid, liquid, gas.
The energy/heat being added to the liquid is used to convert the liquid into a gaseous state, rather than to heat the liquid (you get something similar when you melt ice). Once a gas, the temperature of the substance will start rising further if heat continues to be applied.
yes viscosity is a property of gas
Relative viscosity is defined as ratio of viscosity of solution to that of a pure solvent.
A pure liquid is a liquid that is not contaminated with any other compound. If water is pure water, then it is a pure liquid. However, shampoo is not a pure liquid.
The best method is chemical analysis.
You can change the viscosity of honey by adding water. While you will no longer have pure honey, the water will change its viscosity. The viscosity of pure honey is approximately 10,000 cP at 20°C and at 1 atmosphere. However, this will vary with the type of honey you have.
A pure liquid is a liquid that is not contaminated with any other compound. If water is pure water, then it is a pure liquid. However, shampoo is not a pure liquid.

no shampoo is not a pure liquid
If you mean physical state, than it is liquid. There are three states of matter, mainly solid, liquid and gas.
The short answer is no. Microorganisms are just that - microscopic, and the naked eye can not determine between different species, especially in a broth culture. Maybe on a plate, where the colony shapes, sizes, viscosity, and color can be determined, but a broth culture usually needs to be streaked onto a plate to determine if it is pure or not.
Pure Substances Boil at a Constant Temperature while Mixtures do not, To determine if the Distillate is pure the Liquid distillate would be boiled and for example if the substance is water, it should begin boiling at exactly at 100 degrees celcius if it boils below or above that point it is not a pure substance
Yes.
