What is the analogy for viscous?
Viscous is to thick as watery is to thin.
Is blood Viscous or non viscous?
Blood is viscous, as it contains a hugely populous density of red blood cells therefore making it viscous. A comparison would be to water, which is less than 3 times as viscous as blood, as it contains around less than 3 times the amount of molecules than in blood.
Is glass viscous at room temperature?
Glass is not considered viscous at room temperature. It is a solid material that does not flow or deform over time like a viscous liquid would.
What liquid is less viscous than water?
Liquid nitrogen is less viscous than water.
Does Pascal's law apply to viscous fluids?
No, Pascal's law applies to non-viscous (incompressible) fluids. Viscous fluids have internal friction that causes them to resist flow and deform. This results in a different behavior compared to non-viscous fluids governed by Pascal's law.
Why glycerol is more viscous then ethyl alcohol?
Glycerol (Glycerin) contains three 'OH' groups at adjacent carbon atoms so the chances of ' hydrogen bonding' are higher than normal alcohols and such a liquid is denser than ethyl alcohol so it is more viscous.
Why is glycerol solid at room temperature?
Glycerol is a solid at room temperature because it has a high melting point of around 18°C. The intermolecular forces between glycerol molecules are relatively strong, which allows them to pack closely together in a solid form.
What is the viscosity of glycerol at 37 degrees?
The viscosity of glycerol at 37 degrees Celsius is approximately 1488 centipoise. Glycerol is a highly viscous liquid at room temperature, with its viscosity decreasing as the temperature increases.
Does glycerol have a higher viscosity than propanol?
Yes, glycerol has a higher viscosity than propanol. Glycerol is a more viscous liquid due to its larger and more polar molecule structure compared to propanol.
What happens if we combine water and glycerol?
When water and glycerol are combined, they form a homogeneous solution without a chemical reaction occurring. The glycerol dissolves in water due to its polar nature, creating a viscous liquid. This mixture is commonly used in various applications such as in skincare products and pharmaceuticals.
What structural feature of glycerol is important in the formation of fats?
The three hydroxyl (OH) groups in glycerol allow it to form ester linkages with fatty acids, leading to the formation of fats through dehydration synthesis. This ensures that fats have a glycerol backbone with fatty acid chains attached to it.
What is a Colourless viscous liquid a by-product of soap and used to make antifreeze?
Propylene glycol is a colorless viscous liquid that is a common by-product of soap production and is utilized in the manufacturing of antifreeze due to its ability to lower the freezing point of water.
Is water heavier than glycerol?
The 3 hydroxyl groups in glycerine/glycerol form intermolecular hydrogen bonds. this strong intermolecular attractions causes it to be a viscous liquid.
What are the elements in glycerol?
Glycerol is the 3-carbon alcohol, C3O3H8.Glycerol: Molecular Formula: C3H5(OH)3Glycerol is an organic compound, also commonly called glycerin or glycerine. It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. Glycerol has three hydrophilic hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature. The glycerol substructure is a central component of many lipids. Glycerol is sweet-tasting and of low toxicity.
Is oxygen found in glycerol?
Glycerol is CH2OHCHOHCH2OH and so, yesit does contain oxygen.
Explain.Glycerol is more viscous than ethanol?
By definition, to overcome viscosity we need to apply enough kinetic energy to overcome the intermolecular forces of attraction of a substance. The harder it is to overcome this, the more viscous the substance is. And we all know that hydrogen bonds are the toughest intermolecular bonds to break. This being said if we look at the ethanol molecule it has one hydrogen bond to ether's none. Therefore, more kinetic energy would be required to overcome the attractions by that bond thus increasing the average kinetic energy needed by the substance to overcome or reduce its viscosity.
Physical properties of glycerin?
It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. For human consumption, glycerol is classified by the FDA among the sugar alcohols as a caloric macronutrient.Its surface tension is 64.00 mN/m at 20 °C , and it has a temperature coefficient of -0.0598 mN/(m K). The glycerol substructure is a central component of many lipids. Glycerol is sweet-tasting and of low toxicity.
