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.
No, hexane is less dense than ethanol- hexane has a density of 0.6548g/mL and ethanol has a density of 0.789g/mL, so hexane will float on top of 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.
Yes, the reaction of ethanol with sodium is generally more vigorous than water with sodium. This is because ethanol is more polar than water, allowing it to facilitate faster reactions. Ethanol also has a lower dielectric constant, which promotes higher reactivity with sodium.
yes, it is much more soluble in ethanol than in water.
A paper clip does not float on ethanol because the surface tension of ethanol is not enough to support the weight of the paper clip. Evelyn Biologist
Ethanol is more viscous than water because it has stronger intermolecular forces due to the presence of a longer carbon chain in its molecule. These stronger forces make it more resistant to flow, resulting in higher viscosity compared to water.
Water is more viscous than methylated spirits, and vegetable oils are more viscous than water.
Acetone is more volatile than ethanol.
Ethanol is less viscous than ethylene glycol at the same temperature. This is because ethanol only has one -OH group, which is responsible for viscosity.
Toothpaste is more viscous because it flows less freely than milk.
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.
Ethanol has dipole moment in the C-O bond and the carbon part of it has London Disperse force, whereas water has only hydrogen bond. So ethanol has more intermolecular force than water, making it more viscous than water. Meanwhile, ethanol has less boiling point than water because London disperse force is easily disrupt by heat.
the intermolecular attractionsis account for this behaivour of honey.
Blood viscosity is a measure of overall blood thickness. Therefore, there is no one place in the body where blood is more viscous than others. However, factors such as cholesterol, smoking, or some illnesses your blood may be more viscous than normal.
No, hexane is less dense than ethanol- hexane has a density of 0.6548g/mL and ethanol has a density of 0.789g/mL, so hexane will float on top of ethanol.
No, basaltic lavas are typically hotter and less viscous than andesite lavas. Basaltic lavas have lower silica content, which results in their lower viscosity and ability to flow more easily. Andesite lavas, on the other hand, have higher silica content and are more viscous.
Basaltic lavas are generally hotter and less viscous than andesite lavas. Basaltic lavas have lower silica content, which makes them flow more easily. Andesite lavas, on the other hand, have higher silica content, making them cooler and more viscous.
