Has a greater viscosity?
Andrew Campbell
Score: 4.1/5 (73 votes)
A fluid that is highly viscous has a high resistance (like having more friction) and flows slower than a low-viscosity fluid. To think of viscosity in everyday terms, the easier a fluid moves, the lower the viscosity. ... Honey would move slower than water, so honey would have a greater viscosity.
What are the greater 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.
Which of the following has greater viscosity?
Mercury is a substance has greatest viscosity.
Which fluid has a higher 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.
Which one is more viscous?
Honey is more viscous than water can you suggest why? Hint: Viscosity of a fluid is higher in which intermolecular forces are more. The liquids in which there are less intermolecular forces results in less viscosity of the liquid.
Understanding Viscosity
Is water high or low 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.
Which of the following is the most viscous fluid?
Water, mercury, and kerosene are easily flowable liquids so they can be eliminated. So, glycerine is found to be the most viscous liquid.
How do you rank viscosity?
The higher the viscosity, the slower the liquid flows through the tube and the steel balls fall. Viscosity is expressed in units of the poise (mPa•s); the higher the number, the higher the viscosity.
Is high viscosity fast or slow?
Viscosity is a measure of resistance to liquid flow. Thus, a higher value means it has more resistance and thus flows more slowly.
What has the smallest viscosity?
Mercury has the lowest kinematic viscosity. Of liquids, ammonia has lower absolute viscosity that water and gasoline has lower kinematic viscosity than water.
Will have the higher viscosity because in terms of size it has?
Viscosity increases with increasing molar mass (and increasing magnitude of dispersion forces) and increasing length (and increasing potential for molecular entanglement). Viscosity also depends on temperature because thermal energy partially overcomes the IMF, allowing molecules to flow past each other more easily.
What causes high viscosity?
An increase in blood viscosity can be caused either by a deformity of the shape of red blood cells (RBCs) which causes RBC aggregation and decreased blood flow or by any pathological elevation of the components of blood. This includes RBC, WBC, platelets, or serum proteins.
What has lower viscosity than water?
Acetone has a viscosity 3x less than water but weighs 2.5 times more.
Does viscosity increase with mass?
With the increasing molecular mass of a liquid, the viscosity increases. The flow of molecules is inversely proportional to its mass. Hence, liquids with high molecular mass possess greater viscosity.
What viscosity is water?
The viscosity of water is 1.0016 millipascals⋅second at 20 °C. That is for its dynamic viscosity. Water viscosity varies depending on its temperature, and the higher the temperature is, the less viscous water is. Water's viscosity at, let's say, 80 °C is 0.354 millipascals-second.
Which has higher 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 liquid is the least viscous?
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. Engineers, doctors, volcanologists, and scientists all use viscosity in practical life.
What is the thickest liquid?
We're home to the famous Pitch Drop experiment, which holds the Guinness World Record for the longest-running laboratory experiment. The experiment demonstrates the fluidity and high viscosity of pitch, a derivative of tar that is the world's thickest known fluid and was once used for waterproofing boats.
Which is more viscous water or methanol?
Water has higher viscosity than methanol because intermolecular forces (hydrogen bonding) are stronger in water than in methanol.
Does honey have a high viscosity?
Viscosity is the measure of resistance of a fluid to flow. 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 has highest viscosity blood or honey?
The correct answer is Honey. Viscosity: S I unit: Pascal seconds (Pa·s) or kg·m−1·s−1. It is the property of a liquid representing the internal resistance of its different layers to motion.
Which is more viscous 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.
Is anything thinner than water?
A non-dense, non-viscous liquid like water will appear "thinner" than a dense, viscous liquid like molasses. The viscosity of water is 8.90 × 10−4 Pa·s at 25C, the viscosity of acetone is 3.06×10−4 at 25C. In my interpretation of your wording, this would make it seem like a thinner liquid than water.
What does viscosity depend on?
The viscosity of a liquid usually depends on its temperature. Viscosity generally decreases as the temperature increases. Viscosity generally increases as the temperature decreases. The viscosity of a liquid is related to the ease with which the molecules can move with respect to one another.
Why is high viscosity bad?
But there may be another critical blood-related issue to consider — blood viscosity, or blood thickness. According to a health report from Harvard University, people with thicker, more viscous blood may be at a greater risk for a heart attack or for developing heart disease.
