what are the main cause of liquid viscosity
Answers
Answer:
Kindly ckeck below___
Explanation:
Factors Affecting Viscosity:
Temperature:. The viscosity of liquids decreases by about 2% for each degree rise in temperature.
Chemical Composition:. The viscosity of liquids generally depends upon the size, shape and chemical nature of their...
Colloid Systems:. The viscosity of lyophilic colloid solution is generally relatively high.
Suspended Material:. Suspended particles cause an increase in the viscosity. The viscosity of blood is important in...
Answer:
Due to strong cohesive forces between the molecules, any layer in a moving fluid tries to drag the adjacent layer to move with an equal speed and thus produces the effect of viscosity as discussed earlier. Since cohesion decreases with temperature, the liquid viscosity does likewise.
