The more viscous (or thick) a liquid is, the longer it will take for an object to move through the liquid. In our experiment, the marbles took longer to sink when dropped into the jars filled with corn syrup and honey than they did when dropped into the jars filled with water and cooking oil.
Which flows faster oil or water?
Above the no-slip line (H W > WC), the oil phase flows faster than the water phase . ... At these conditions, which correspond to dispersions of oil-in-water with a water layer (DO/W&W), the water phase flows faster than the oil phase.
Which liquid marble flows the fastest slowest?
What will happen and why? Answer: The marble will drop the fastest in the water and slowest in the glycerol . The reason is due to the different viscosities of the fluids.
Which liquid has the highest viscosity science fair project?
Out of all the liquids I tested ( honey , water, milk, cooking oil, glycerin, hand sanitizer, and syrup), honey is the most viscous and milk is the least. During my observations, I found out that honey and hand sanitizer were very close compared to other liquids but at the end, honey beat hand sanitizer.
What is the least viscous fluid?
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.
Why marble dropped faster in water than dishwashing liquid?
You should have observed that the marbles fell more slowly through more viscous liquids (such as syrup) than through less viscous liquids (such as water). This is because the more viscous liquids have more resistance to flow , making it more difficult for the marble to travel through them.
Which liquid flows the fastest?
Studies of the superhot material, first done about a decade ago, have revealed QGP is the hottest, least viscous known liquid and is capable of forming the smallest drop of liquid ever seen. And now, it’s also the fastest known spinning liquid, as reported in August by the STAR collaboration in Nature.
Which liquid has 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 more viscous honey or ketchup?
| Approximate Viscosities of Common Materials (At Room Temperature-70°F) * | Material Viscosity in Centipoise | Honey 10,000 cps | Ketchup 50,000 cps | Sour Cream 100,000 cps |

Which liquid has more 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 has higher viscosity water or oil?
More thick a liquid is, more slowly it will flow’. There is no relationship between viscosity and density of a fluid. ... 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 increases the viscosity of a liquid?
Both cohesion and molecular interchange contribute to liquid viscosity. The impact of increasing the temperature of a liquid is to reduce the cohesive forces while simultaneously increasing the rate of molecular interchange. The former effect causes a decrease in the shear stress while the latter causes it to increase.
What is the viscosity of glycerin?
| Liquid Specific Gravity @ 16°C Absolute Viscosity cP | Glycerine 100% 1.26 at 20°C 648 | Glycerine 100% 176 | Isopropyl Alcohol 1.11 1.9 | Lacquer 25% Solids 3000 |

Which liquid travels the slowest which liquid travels fastest?
Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases , faster through liquids, and fastest through solids. Temperature also affects the speed of sound.
What is the thinnest liquid in the world?
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 same viscosity as blood?
At normal body temperature (37 degrees Celsius), blood is four times more viscous than water but only slightly denser. As a result, it flows more slowly and it is stickier than water. Corn syrup or honey , on the other hand, are far more viscous (more than thousand times) than blood.
