Which is the least viscous water or oil?
When you mix oil and water, oil tends to spread as a thin film on the top of the water surface since water is much denser than oil. But oil is more viscous than water and thus when when we put a drop of water and oil on a slant surface, water will move downwards more quickly than the oil drop.

What is a low viscosity?
Fluids with low viscosity have a low resistance and shear easily and the molecules flow quickly; high viscosity fluids move sluggishly and resist deformation. Some liquids, like pitch, glass and peanut butter, have such high viscosity they behave like solids.
Is water low viscosity?
Viscosity is often referred to as the thickness of a fluid. You can think of water (low viscosity) and honey (high viscosity).
Which of the below has the highest viscosity?
The correct answer is Honey.

Mercury has the lowest kinematic viscosity. Of liquids, ammonia has lower absolute viscosity that water and gasoline has lower kinematic viscosity than …
Which of the following is more viscous?
So glycerol is the most viscous.
What has a lower viscosity than water?
8cST) fluid. Everything I have come across that is low viscosity is inflammable – acetone, ether, silicone oil, fuel, etc. I have found some confusing things in my research. Acetone has a viscosity 3x less than water but weighs 2.5 times more.
Is diesel less viscous than water?
Liquids of very low viscosity are the mobile liquids eg. kerosene, diesel, petrol.
Which is more viscous alcohol or water?
Rubbing alcohol molecules (2-propanol) are significantly larger than those of water, so their greater London forces result in a higher viscosity.
What is viscosity of liquid?
Viscosity is the resistance of a fluid (liquid or gas) to a change in shape or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow.

What is the thinnest liquid?
Thanks to the “super material” graphene, a team of researchers managed to create one of the world’s thinnest layers of liquid. There’s now a new understanding of the word “wet” thanks to physicists who created the thinnest film of liquid ever.
What liquids have high viscosity?
Liquids which flow very slowly, like glycerin or honey, have high viscosities. Those like ether or gasoline which flow very readily have low viscosities. Viscosity is governed by the strength of intermolecular forces and especially by the shapes of the molecules of a liquid.
Does oil have low viscosity?
Thin oils have lower viscosity and pour more easily at low temperatures than thicker oils that have a higher viscosity. Thin oils reduce friction in engines and help engines start quickly during cold weather. Thick oils are better at maintaining film strength and oil pressure at high temperatures and loads.
How do you describe a liquid with a low viscosity?
In terms of a more technical definition, low viscosity liquids have less resistance to flow when they are subject to shear stress. The viscosity of a liquid is related to how well its layers move in relation to each other. The layers of a low viscosity liquid move easily because there is less friction between them.
Does glycerol have high viscosity?
Glycerol contains 3 −OH hydroxyl groups. This means that the intermolecular forces are much greater because of these many hydrogen bonds. Therefore the viscosity increases.
What is oil viscosity?
It governs the sealing effect of oils and the rate of oil consumption, as well as determines the ease with which machines may be started or operated under varying temperature conditions, particularly in cold climates. Viscosity is a measure of an oil’s resistance to flow.
What is the viscosity of glycerol?
Considering the following example from our measurements: for glycerol at 383.29 K, using spindle SSA/18 at N = 100 RPM the measured viscosity was 11.10 mPa·s.
Which has the highest viscosity Brainly?
Expert-verified answer
The viscosity of the thick liquid is higher, whereas gases have the lowest viscosity. Honey is thick, so its viscosity is higher.
What is the thinnest liquid?
Thanks to the “super material” graphene, a team of researchers managed to create one of the world’s thinnest layers of liquid. There’s now a new understanding of the word “wet” thanks to physicists who created the thinnest film of liquid ever.
What liquid has the most viscosity?
One of the most viscous liquids known is pitch, also known as bitumen, asphalt, or tar. Demonstrating its flow and measuring its viscosity is the subject of the longest continuously running scientific experiment, begun in 1927 at the University of Queensland in Australia. Prof.

Why does water have the lowest viscosity?
To sum up: Water has a narrow viscosity spectrum (as a function of temperature) because it has a narrow stress relaxation time spectrum. It has a narrow stress relaxation time spectrum because it is a relatively simple, small molecule.
What liquids have high viscosity?
Liquids which flow very slowly, like glycerin or honey, have high viscosities. Those like ether or gasoline which flow very readily have low viscosities. Viscosity is governed by the strength of intermolecular forces and especially by the shapes of the molecules of a liquid.
