Which is more viscous water or olive oil?
Which is more viscous water or olive 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.
Does oil have a higher viscosity than water?
Oil floats on water – the particles in the oil are less crowded than those in water. However, oil is more viscous than water. Oil flows more slowly than water – the particles in the oil are attracted to each other more than the particles in water. Temperature affects viscosity in the same way it affects density.
Is olive oil less viscous?
According to the study, “the lowest viscosity and thermal conductivity values and the highest resistivity values were found for oils that were obtained from olives harvested by hand.” Harvesting olives by machine however, proved to have higher levels of thermal conductivity with lower levels of resistivity.
Why is olive oil so viscous?
The viscosity of a liquid is related to its temperature The viscosity of some liquids changes a great deal as the temperature increases. Olive oil, for example, is more viscous at 20°C than 60°C. The oleic acid molecules that are in olive oil are made up of carbon, hydrogen, and oxygen atoms.
Which has highest viscosity?
For instance, honey has a much higher viscosity than water. Viscosity is measured using a viscometer. Measured values span several orders of magnitude. Of all fluids, gases have the lowest viscosities, and thick liquids have the highest.
Which is more viscous water or honey?
So, we can say that intermolecular forces decide the viscosity of the fluid. – In water, only water molecules are there. That results in the resistance to the deformation in the fluid. So, we can say that due to more intermolecular forces, honey is more viscous than water.
Which oil has the highest viscosity?
Rice bran oil was the most viscous (0.0398 Pa·s at 38°C) while walnut oil was the least viscous (0.0296 Pa·s at 38°C) among the oils studied.
Is honey viscous?
A fluid that is highly viscous has a high resistance (like having more friction) and flows slower than a low-viscosity fluid. Honey would move slower than water, so honey would have a greater viscosity.
Which is more viscous water or ethanol?
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 liquid has lowest viscosity?
Water, gasoline, and other liquids that flow freely have a low viscosity. Honey, syrup, motor oil, and other liquids that do not flow freely, like those shown in Figure 1, have higher viscosities.
Which is most viscous blood or honey?
… The higher the viscosity of a material, the slower the flow speed for given forces will be. Honey, for instance, has a viscosity between 2.54 and 23.4 Pa · s (at 25°C, depending on moisture and sugar composition) [46] , while blood has 4 mPa · s [47]. …
What is the most viscous liquid?
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.
Why is oil so much more viscous than water?
# oil is more viscous than water because of the strong intermolecular force of attraction in oil which causes more internal friction therefore more viscosity! Q: Why is oil more viscous than water?
Which is more viscous, acetone or water?
Acetone has a viscosity 3x less than water but weighs 2.5 times more. Accordingly, why is syrup more viscous than water? Viscosity is the property of a given liquid that describes its resistance to flow. A highly viscous fluid tends to be thick, like honey or cold maple syrup.
Why is the viscosity of mercury greater than that of water?
The dynamic viscosity of mercury is greater than water. See this table: The kinematic viscosity is the dynamic viscosity divided by the density. Mercury is a lot denser than water, so its kinematic viscosity is lower than the kinematic viscosity of water. But that’s just because mercury is very dense.
Why is viscosity a property of a liquid?
Viscosity is property of fluid (in motion) by virtue of which it provides restrictions in flow. Viscosity of liquid depend upon cohesive force where as in gas it depend upon molecular interaction. Cohesive force represent intermolecular forces of attraction.
