How could you change the viscosity of the substances?
Cooling a fluid increases the viscosity. Otherwise, to thicken it or increase the viscosity, requires the addition of another chemical.
How do you change the viscosity of honey?
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.
How does temperature affect viscosity of motor oil?
Yes. If the temperature changes enough, the viscosity of oil will change, too. Oil is designed to resist changes in viscosity with temperature changes, at least to a degree. But if the change (either hotter or colder) is extreme, then the viscocity will most certainly change. And, as you'd expect, as it gets hotter, the viscosity of oil decreases (it get thinner), and as it gets colder, the viscosity of oil increases (it gets thicker).
What is mooney viscosity?
The measurement used to quantify change in a thermoset or thermoplastic elastomer material's viscosity from its uncured state as it transitions to a cured or "scorched" state.
Are the clues that indicate a chemical change always reliable?
Some indicators of a chemical reaction are:- change of color- change of odor- release of a gas- change of the temperature- change of the viscosity- formation of a precipitate- change of general appearance- possible explosion - possible chemiluminescence - formation of new compounds
Predict the change in viscosity as heat is added to or removed from a sample of oil?
think of it as this viscosity is thick when it is heated what will happen
How does heat affect viscosity?
Heat decreases viscosity. Lower viscosity means thinner like water. An example of higher viscosity would probably be honey.
How could you change the viscosity of the substances?
Cooling a fluid increases the viscosity. Otherwise, to thicken it or increase the viscosity, requires the addition of another chemical.
How would you define viscosity - index?
The viscosity index refers to the measure of the change of viscosity with a change in temperature.
What affects the viscosity of a molten material?
viscosity is affected by heat and water.by adding water viscosity decreases,by heating viscosity increases....
Is viscosity a chemical or a physical change?
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.
When you heat a substance how does it affect its viscosity?

how is knowledge of viscosity is applied to real life?
Viscosity plays a significant role in the preparation and serving of food. Cooking oils may or may not change viscosity as they heat, while many become much more viscous as they cool. Fats, which are moderately viscous when heated, become solid when chilled.
Will heat always reduce the viscosity of a fluid?
yes
What happens to viscosity of a liquid when you heat it?
It becomes less.
