- This is the property of liquids and gases both.
- In the case of liquid, it is seen because of the cohesive force between the molecules of the liquid.
- In case of a gas, it is seen because of the diffusion of its molecules from one layer to other layers.
- The viscosity of gases is very less than that of liquids.
- No viscosity is there in solids.
- Viscosity on an ideal fluid is always zero.
- The viscosity of liquids decreases with the rise in temperature.
- The viscosity of gases increases with the rise in temperature.
EXPLANATION:
is used as the symbol for viscosity. So option 3 is correct.
