It does change. Check Table 2 in the related link.
yes
The viscosity index refers to the measure of the change of viscosity with a change in temperature.
The kinematic viscosity of a fluid is found by dividing the dynamic viscosity by the density of the fluid. The kinematic viscosity of water changes depending on the temperature of the water. It ranges from .29 SI units to 1.787 SI units.

Heat decreases viscosity. Lower viscosity means thinner like water. An example of higher viscosity would probably be honey.
yes
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.
The viscosity of a substance will change with both temperature and pressure. For liquids the changes induced by a change in temperature are usually more readily observed than the changes from pressure because liquids are only slightly compressible with pressure. In gasses, the changes in viscosity with pressure are much more easily demonstrated because gases are, almost by definition, quite compressible so that the density can be easily changed by either changes in pressure or changes in temperature.
The viscosity index refers to the measure of the change of viscosity with a change in temperature.
As with pretty much all liquids, the viscosity of water at a constant temperature increases with increasing pressure. Since the pressure squeezes the molecules closer together this is to be expected. See the related link below for some actual values for this phenomenon.
As temperature increases viscosity decreases.
The viscosity is similar to the viscosity of water.
If something has a greater viscosity, it becomes more 'runny' compared to its original state when heated up. The greater the change from thick to runny = the greater the viscosity. So honey has a greater viscosity than water for example.
For example the viscosity of water.
There are a few ways to increase the viscosity of water. One thing to add to water to increase viscosity is sugar.
Viscosity. :)
viscosity is a physical characteristic not a physical change. it is the thickness of a substancephysical changes would be if it turned from solid into a liquid.for example a chocolate bar goes through a physical change when it becomes melted chocolate.
