The main factor that affects the viscosity of a liquid is the intermolecular force of attraction. But there are other factors too, like- shape of individual molecules or the temperature. By looking at these values, it can be concluded that Glycerine is the most viscous substance from the given list.
Which of these liquids has the highest viscosity?
Syrup has the highest viscosity.
What is high viscosity?
High viscosity means that the thickness of the material is very thick compared to low viscosity which is rather thin. Liquids like water have a much lower viscosity compared to liquids such as honey.
Which alkane has the highest viscosity?
Because octane has a longer carbon chain than pentane, the dispersion forces are even stronger, and octane has a higher viscosity. In conclusion, the alkane with the greatest viscosity is octane, or answer choice (A).What is the viscosity of hexane?

Which has a higher viscosity pentane or butanol?
Butanol has stronger intermolecular forces than pentane because it has the ability to form hydrogen bonds, which would contribute to a higher viscosity. … However, the viscosity at 20 C of butanol is 2.948 cP, and the viscosity of pentane is 0.240 cP.What is example of viscosity?
According to Wikipedia, viscosity is the friction between the molecules of fluid. For example, when a fluid flows through a tube, the fluid will move more quickly near the center of the tube axis but move more slowly along the walls of the tube. This is because of the friction with the walls.
Is glycerol a viscous liquid?Glycerol, CH2OHCHOHCH2OH, is viscous partly because of the length of the chain but also because of the extensive possibilities for hydrogen bonding between the molecules.

What liquid is thinner than water?
Examples include rubbing alcohol, but also motor oil, mineral oil, or corn oil. Some of these are more viscous than water but they float on water. If by “thinner” you mean both less dense and less viscous, then rubbing alcohol would be the best answer off the top of my head.
Which has more viscosity water or mercury?
Detailed Solution. Viscosity: It is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress. It is denoted by μ. The dynamic viscosity of mercury is greater than water.
Which is the least viscous?
The least viscous at any temperature must be superfluid liquid helium.

What is oil viscosity?
Engine oil viscosity refers to how easily oil pours at a specified temperature. Thin oils have lower viscosity and pour more easily at low temperatures than thicker oils that have a higher viscosity. … Thick oils are better at maintaining film strength and oil pressure at high temperatures and loads.
Which viscosity is thicker?
In layman’s terms, viscosity defines a fluid’s resistance to flow. The higher the viscosity of a liquid, the thicker it is and the greater the resistance to flow. Temperature will affect the viscosity of most materials.
What are viscosity 3 examples?
- Honey.
- Engine Oil.
- Brake Oil.
- Lubricant.
- Cooking Oil.
- Liquid Soap.
- Printing Ink.
- Super Glue.
Where is viscosity used?
Viscosity measurements are used in the food industry to maximize production efficiency and cost effectiveness. It affects the rate at which a product travels through a pipe, how long it takes to set or dry, and the time it takes to dispense the fluid into packaging.
Does Solid have viscosity?
The concept of deformations of solids under loading has a long history. It just isn’t called ‘viscosity’ – instead this is just part of the mechanical properties of solids.
What is viscosity of ccl4?

What is viscosity of butanol?
36.1 cP at -50.9 deg C; 5.186 cP at 0 deg C; 2.544 cP at 25 deg C; 0.533 cP at 100 deg C.
What is the viscosity of IPA?

Can we eat glycerin?
Since glycerin is a form of sugar alcohol that your body cannot fully absorb, consuming too much — either alone or through foods — may also lead to gas and diarrhea. Vegetable glycerin is generally considered safe.
What is molecular viscosity?
At a molecular level, viscosity is a result the interaction between the different molecules in a fluid. This can be also understood as friction between the molecules in the fluid. Just like in the case of friction between moving solids, viscosity will determine the energy required to make a fluid flow.
Does glycerol have high viscosity?
Glycerol is has 3 OH groups . Which means to one molecule can atleast form 6 hydrogen bonds. This means that the intermolecular forces are much greater because of these many hydrogen bonds. … That is why, glycerol has a higher viscosity than water.
Is ethanol high viscosity?
We found in an experiment using Ostwalds method that ethanol is more viscous than water, which is already surprising as water has stronger intermolecular bonds than ethanol as @MaxW pointed out. The mixture of both substances furthermore is significantly more viscous than both individual substances.
What is CH3CH2OH?
Ethanol, CH3CH2OH, is an alcohol, a group of chemical compounds whose molecules contain a hydroxyl group, –OH, bonded to a carbon atom. Ethanol is a colorless, flammable, chemical compound. It is found in alcoholic drinks.
What is the viscosity of toluene?
The proposed value for the viscosity of liquid toluene at 298.15 K and 0.1 MPa is η = 554.2±3.3 μPa s.
Is petrol thinner than water?
Hope this clarified anything! Water is denser than petrol, so there essentially more molecules of water in a given volume. For example in a given volume, there may be 15,000 molecules of petrol but 20,000 molecules of water.
Is vinegar thinner than water?
Water has a density of about one gram per cubic centimeter (depending a little on temperature and pressure). Household vinegar consists almost entirely of water, but with some acetic acid molecules dissolved in it. In general, dissolving stuff in water makes it more dense, making vinegar the densest of the three.
