because of the intermolecular forces.at 50% the OH ions of ethanol and OH ions of water are maximum and they interact while after this % the viscosity of ethanol itself starts dominating as the pure ethanol is less viscous so viscocity goes on decreasing!

How does silica content and viscosity effect igneous rocks?
As silica content increases viscosity increases.
How adding water affects viscosity?
it increases mass in same volume, therefore density(viscosity) increases =)
How does viscosity of liquid vary with rise in temperature?
As the temperature increases, the viscosity of the liquid will decrease.
Does an increase in silica increase the viscosity of magma?
Yes. Viscosity is the resistance of a fluid to flowing. A high viscosity means low flowing (I specifically mention this because this is a huge pitfall) When silica content increases, and when temperature decreases, the viscosity of a magma increases along with it.
What does increased blood viscosity mean?
Yes. As the blood increases in viscosity, the heart is required to increase the amount of pressure it takes to push the blood through the vasculature; thus the blood pressure increases
What is the relationship of viscosity and concentration?
as concentration increases, viscosity increases
What is the effect of temperature on the viscosity of gases?
For liquids; Viscosity tends to fall as temperature increases. For gas; Viscosity increases as temperature increases.
How do you increase viscosity?
Viscosity is the resistance of a liquid to flow. When temperature decreases Viscosity generally increases. Viscosity generally decreases when the temperature increases.
Will ethanol have a greater viscosity than ethylene glycol at the same temperature?
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.
How does silica content and viscosity effect igneous rocks?
As silica content increases viscosity increases.
How adding water affects viscosity?
it increases mass in same volume, therefore density(viscosity) increases =)
What is the relationship between pH and viscosity?
As pH increases so does viscosity
What is the viscosity of ethanol?
Viscosity of EthanolThe dynamic viscosity of ethanol varies with temperature (and pressure). At 25 degrees Celsius (and one atmosphere), it is 1.074 cP (1.074 mPa-s). Compare that to water's viscosity: 0.894 cP. At 20 degrees Celsius, the viscosity of ethanol increases to 1.20 cP.For further comparison, here are some other familiar liquids with lesser and greater viscosity.Corn syrup: 1381 cPMotor oil (SAE 40): 319 cPOlive oil: 81 cPEthylene glycol (antifreeze): 16.1 cPMercury: 1.526 cPMethanol: 0.544 cPAcetone: .306 cPcP (centipoise) = mPa-s (millipascal-second).
What affects the viscosity of a molten material?
viscosity is affected by heat and water.by adding water viscosity decreases,by heating viscosity increases....
How are viscosity and temperature related?
For most liquids viscosity decreases as temperature increases.
What happens when the temperature-of lava increases?
When the temperature of lava increases, its viscosity will decrease. Viscosity is a measure of the magnitude of internal friction of a substance.
What is the relationship between temperature and viscosity?
There is an inverse relationship between temperature and viscosity. That is, as the temperature increases, the viscosity decreases (the fluidity increases. However, the exact nature of the relationship is far from straightforward.
