Which Is More Viscous Water Or Alcohol?

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.

Is alcohol less viscous than water?

The viscosity of pure alcohols and aqueous solutions is found to increase almost linearly with increasing pressure, whereas that of

water decreases slightly with pressure at temperatures below 298

K.

Which is more viscous water or methanol?

Why does a

Methanol/Water mixture

have a higher viscosity than both of the liquids? … One explanation is that the intermolecular forces of the liquids become stronger, which prevents the sliding of molecules past each other and results in a more viscous fluid.

What is the viscosity of alcohol?

What liquid is more viscous than water?

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.

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.

What liquid has 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 highly viscous?

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.

Is water viscous?

Viscosity is the property of fluid having high resistance to flow. We normally think of liquids like honey or motor oil being viscous, but when compared to other substances with like structures,

water is viscous

. … Water molecules are very cohesive because of the molecule’s polarity.

Which is the most viscous ch3oh?

Methanol has less viscosity than

water

. That means water is more viscous than methanol.

Why is alcohol viscous?

Since the polar hydrogen of

one alcohol can hydrogen bond with

the oxygen of another molecule, there is a good deal of intermolecular hydrogen bonding in alcohols. … That is just what is observed – glycerol is far more viscous than water or simple alcohols such as methanol or ethanol, whose viscosity is much like water.

How is viscosity calculated?

There are several formulas and equations to calculate viscosity, the most common of which is

Viscosity = (2 x (ball density – liquid density) x g x a^2) ÷ (9 x v)

, where g = acceleration due to gravity = 9.8 m/s^2, a = radius of ball bearing, and v = velocity of ball bearing through liquid.

What is viscosity of ethanol?

Viscosity.

6.285 mPa·s

.

at −50 °C

.

4.656 mPa·s

.

Is acetone more viscous than water?

Acetone has a

viscosity 3x less than water

but weighs 2.5 times more.

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.

Is oil more viscous than water?

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.
