What is the most viscous?

So, glycerine is found to be the most viscous liquid.

What is a viscous gas?

The viscosity of a gas can be thought of as a measure of its resistance to flow and is measured in the CGS unit Poise = dyne sec/cm2. The viscosity of gases near room temperature are in the centiPoise range, so that is a commonly used unit. Gas viscosity is only weakly dependent on pressure near atmospheric pressure.

Which substance is more viscous?

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 liquid would be the most 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.

Which is the least viscous?

The least viscous at any temperature must be superfluid liquid helium.

Which is more viscous water or methanol?

Methanol has less viscosity than water. That means water is more viscous than methanol. This is because the hydrogen bonding in water is more stronger than the bonding in methanol, which increases the intermolecular attractions thereby making water more viscous.

Is ideal gas viscosity?

From dimensional analysis I find that the dynamic viscosity of an ideal gas must depend on its pressure p, density ρ and mean molecular free path l in this way: μ=C√ρpl. Here, C≥0 is a non-dimensional constant.

What is Thomson effect?

Joule-Thomson effect, the change in temperature that accompanies expansion of a gas without production of work or transfer of heat. At ordinary temperatures and pressures, all real gases except hydrogen and helium cool upon such expansion; this phenomenon often is utilized in liquefying gases.

What is an example of high viscosity?

Fluids with low viscosity have a low resistance and shear easily and the molecules flow quickly; high viscosity fluids move sluggishly and resist deformation. Some liquids, like pitch, glass and peanut butter, have such high viscosity they behave like solids. For example, water at 20°C has a viscosity of 1.002 cPs.

What is the most non viscous fluid?

Superfluid helium has zero viscosity. There are no chemical reactions connected with superfluidity. In fact, helium as a noble gas does not undergo any chemical reactions at all. Superfluidity only occurs at very low temperatures near the absolute zero.

What is the least viscous gas in the world?

The least viscous gases on my list are pentane and propane. If there is a pattern it would appear to favour monatomic gases for high viscosity and vice versa. Gas viscosity increases with temperature, the opposite of what most liquids do, and oddly enough gas viscosity is practically independent of pressure.

What are the different viscosities of liquids and gases?

Viscosity of Liquids and Gases Liquids Viscosity (Poise) Acetone 0.0032 Alcohol(ethyl) 0.012 Blood (whole) 0.04 Blood plasma 0.015 Gasoline 0.006 Glycerine 14.9 Mercury 0.016 Oil (light) 1.1 Oil (heavy) 6.6 Water 0.01 Gases Viscosity (Poise) Air 0.00018 Helium 0.00019 Methane 0.00020 Nitrogen 0.00018 Oxygen 0.00020 Water vapor (steam) 0.00013

What are the most viscous organic substances?

It is one of the most viscous organic substances that can be found in nature. Such viscosity is caused by the elements that comprise it: sulfur, metals, vanadium, lead, mercury, arsenic and selenium; Heavy and viscous elements that when integrated form an even more viscous compound. They are a type of liquid medicine composed of chemicals.

What are some examples of high-viscosity fluids?

One of the most commonly studied high-viscosity fluids is Pitch (resin) – Wikipedia, which at 25 °C has a viscosity of 2.3 × 10 8 P a ⋅ s [ 1], about 20 billion times the viscosity of water. The famous Pitch drop experiment – Wikipedia at a university in Queensland, Australia has been collecting data on this behavior continuously since 1927.
