Is water more viscous than honey?
No, honey is more viscous than water. Viscosity refers to a fluid's resistance to flow, and honey is thicker and stickier compared to water, which makes it more viscous.
Which is more viscous pure water or saline water?
Saline water is more viscous than pure water because the presence of dissolved salts increases the resistance to flow, making it thicker. This higher viscosity can be attributed to the interaction between the salt ions and water molecules, creating more friction as the liquid moves.
Why is water better than ethanol for chromatography?
Water is preferred over ethanol for chromatography because it is more polar and can interact with a wider range of compounds, providing better separation. Additionally, water is a safer and more environmentally friendly solvent compared to ethanol.
What is the difference of absolute ethanol to the regular technical grade ethanol?
Absolute ethanol is 100% pure ethanol, with no water content, making it suitable for laboratory and industrial uses requiring high purity. Technical grade ethanol, on the other hand, may contain impurities and water, making it more suitable for general industrial applications like cleaning and disinfecting.
What is the solubility of methocel?
Methocel, also known as methylcellulose, is soluble in water. Its solubility depends on the grade of methocel used and the temperature of the solvent. Generally, it forms a clear, viscous solution when mixed with water.
Is water more viscous than vegetable oil and methylated spirits?
Water is more viscous than methylated spirits, and vegetable oils are more viscous than water.
Is water more or less viscous than spirits?
Water is less viscous than spirits. Spirits, such as vodka or whiskey, have a higher viscosity due to the presence of dissolved sugars, oils, and other compounds. Water is a more freely flowing liquid due to its simple molecular structure.
Is water more viscous than honey?
No, honey is more viscous than water. Viscosity refers to a fluid's resistance to flow, and honey is thicker and stickier compared to water, which makes it more viscous.
Which is more viscous pure water or saline water?
Saline water is more viscous than pure water because the presence of dissolved salts increases the resistance to flow, making it thicker. This higher viscosity can be attributed to the interaction between the salt ions and water molecules, creating more friction as the liquid moves.
Which liquid expands more Ethanol or Water?
Ethanol expands more than water when heated because it has a higher coefficient of thermal expansion. This means that ethanol will increase in volume more than water when heated to the same temperature.
What is meant by a viscous liquid?
Viscosity is a measure of the thickness or how runny a liquid is. More viscous means thicker and syrup-like. Less viscous means more runny and more like water.
Can a viscous fluid be less dense then fresh water?
Yes, for example oil is less dense than water even though it is more viscous.
Why ethanol viscosity increases after 50?
Ethanol viscosity increases after 50 due to changes in its molecular structure as temperature decreases. At lower temperatures, the molecules in ethanol move more slowly and are closer together, leading to increased resistance to flow and higher viscosity.
Explain.Glycerol is more viscous than ethanol?
Glycerol is more viscous than ethanol because glycerol has a higher molecular weight and stronger intermolecular forces, leading to greater resistance to flow. Ethanol is a smaller molecule and experiences weaker intermolecular forces, resulting in lower viscosity.
Why is water better than ethanol for chromatography?
Water is preferred over ethanol for chromatography because it is more polar and can interact with a wider range of compounds, providing better separation. Additionally, water is a safer and more environmentally friendly solvent compared to ethanol.
What is the difference of absolute ethanol to the regular technical grade ethanol?
Absolute ethanol is 100% pure ethanol, with no water content, making it suitable for laboratory and industrial uses requiring high purity. Technical grade ethanol, on the other hand, may contain impurities and water, making it more suitable for general industrial applications like cleaning and disinfecting.
Why is water a better conductor than ethanol?
Water is a better conductor than ethanol because it contains ions that can move freely and carry electrical charges, while ethanol does not dissociate into ions as readily. This means that water can facilitate the flow of electricity more easily than ethanol.
