Why does the coefficient of viscosity of liquids increase with an increase in temperature?
Wiki User
∙ 9y ago
Temperature measures the speed of random thermal motion on the atomic and molecular level. When sub-microscopic particles are moving faster, the liquid as a whole will be more fluid and less viscous.

How are viscosity and temperature related?
For most liquids viscosity decreases as temperature increases.
How you can increases or decreases viscosity of liquids?
Change its temperature.
Why viscosity increases to decrease temperature?
Viscosity tends to increase as temperature drops in most liquids because the kinetic energy of the molecules reduces. This allows the intermolecular forces to get molecules attracted giving the fluid more resistance to flow. Interesting though, in gases at low pressure viscosity increases with T1/2, where T is the thermodynamic temperature.
How does the density of a liquid affects its viscosity?
denser liquids tend to have more viscosity
How viscosity of liquid depends on temperature?
Viscosity is a liquids resistance to flow. Viscosity decreases as the liquid is heated. Molecular shape of the components making up the liquid can affect viscosity. Small round molecules make little contact and can move more freely making a compound less viscous. The viscosity of a fluid is basically a measure of how sticky it is. Water has a fairly low viscosity; things like shampoo or syrup have higher viscosity. Viscosity also depends on temperature - engine oil, for instance, is much less viscous at high temperatures than it is in a cold engine in the middle of winter.
How the coefficient of viscosity of a liquid changes with temperature?
The coefficient of viscosity of liquids decreases with an increases in temperature.
How are viscosity and temperature related?
For most liquids viscosity decreases as temperature 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.
What is the effect of pressure on viscosity?
As temperature increases viscosity decreases.
How you can increases or decreases viscosity of liquids?
Change its temperature.
Do hotter liquids have more or less viscosity than colder liquids?
Cold water has higher viscosity than Hot water, take note that, as the temperature of fluid increases, viscosity decreases.
What are the examples of semi-liquids?
plasma may be an example of semi liquid and as well as all fluids are semi liquids which have large coefficient of viscosity (eta)
Why viscosity increases to decrease temperature?
Viscosity tends to increase as temperature drops in most liquids because the kinetic energy of the molecules reduces. This allows the intermolecular forces to get molecules attracted giving the fluid more resistance to flow. Interesting though, in gases at low pressure viscosity increases with T1/2, where T is the thermodynamic temperature.
What is the viscosity of caesium?
This question is a non-sequitur. Viscosity is a property of liquids. Caesium is a solid at standard temperature and pressure. If you heated caesium until it was a liquid, the viscosity would decrease as you increased the temperature.
What mainly determines the viscosity of a magma?
Viscosity is the measure of a liquids resistance to flow. In the case of magma, the hotter it is, the lower the viscosity.
How do liquids with a high viscosity differ from a liquids with a low viscosity?
Because liquids with a high viscosity flow slowly as to where a liquid with a low viscosity flow quickly
What is the effect of the temperature on the flow rate and the viscosity of a liquid?
HSP With increase in temp.the viscosity of liquids decreases,thereby increasing the flow rate and vice versa.The decrease in viscosity with rising temp.is due to the fact that the intermolecular attraction decreases and the cohesive forces increases. This does not apply with water
