Which material has the lowest viscosity?
Viscosity describes a fluid’s internal resistance to flow and may be thought of as a measure of fluid friction. Thus, water is “thin”, having a low viscosity, while vegetable oil is “thick” having a high viscosity. What liquid has lowest viscosity? Water, gasoline, and other liquids that flow freely have a low viscosity.

- Newfoundland – 13%
- Northwest Territories – 5%
- Nova Scotia – 15%
- Ontario – 13%
- Prince Edward Island – 14%
- Quebec – 14.975%
What liquid has the lowest 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.
Why does basaltic magma have the lowest viscosity?
Why does basaltic magma have the lowest viscosity? A basaltic lava flow has a low viscosity due to its low SiO2 content. Eruptions associated with basaltic lava usually are not explosive due to the low silica and gas content. Gases escape more easily when silica content is low. Because of the low viscosity, basaltic lava flows spread out, forming extensive layers.
What liquids have the highest 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.
What is high viscosity example?
Some liquids, like pitch, glass and peanut butter, have such high viscosity they behave like solids. In common vernacular, a liquid is said to be “viscous” if its viscosity is substantially greater than that of water, and is described as “mobile” if the viscosity is noticeably less than water.
What is higher viscosity?
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?

What is high viscosity?
High Viscosity refers to the physical property of fluids where fluids have high internal momentum resistance and they resist deformation causing the fluids stuck on the surface and its speed to be too slow.
What happens to fluids with high viscosity?
In high viscosity, the fluids have a strong molecular bond resulting in negligible or almost no transfer of momentum as it is obstructed by viscous force. This results in the slow speed of fluids having high viscosity.
Why does fluid have high internal momentum resistance?
The above observation from the experiment done shows that fluids with high viscosity have high internal momentum resistance, due to which the transfer of momentum is obstructed, and the speed of flow becomes slow and sticky to the surface.
What is the cause of high internal resistance in fluids with high viscosity?
Fluids whose molecules are bonded together with strong forces, i.e., they have strong inter-molecular forces. These strong inter-molecular forces cause high internal resistance in the fluids having high viscosity.
What is the basic property of fluid mechanics?
While exploring the fluid mechanics, you must have encountered the term viscosity. It is widely used as the basic property of fluids.
What is the property of fluids to move sluggishly and resist deformation?
The property of some fluids to move sluggishly and resist deformation is called High Viscosity. Here, we will get to know what is high viscosity in detail.
The science of the viscosity
Every movement is accompanied by friction. When it comes to fluids, one of the most essential terms you’ll come across is viscosity. The relative motion of the fluid layers is referred to as fluid flow. Friction will form between these layers as they move, preventing the flow.
Viscosity of some common fluids
The viscosity of some common fluids is mentioned in the chart below, ranging from low to high.
Why is viscosity important in everyday life?
While pouring oil into your vehicle, you need to take care of its viscosity. Viscosity decides the oil consumption in your vehicle. Moreover, the fluid’s viscosity index is low; then, during summer, it becomes thinner. Thus, you need to use fluid with stable viscosity so that it does not react to heat or cold.
