Explain the effect of density and pressure on the viscosity of liquids

1.	Explain the effect of density and pressure on the viscosity of liquids/gases.
Answer» Liquids: 1. Viscosity increases with increase in density of the liquid. Viscosity increases with increase in pressure (except water). 2. Gases: Viscosity decreases with increase in density. Viscosity decreases with increase in pressure.

Explain the effect of density and pressure on the viscosity of liquids/gases.

Answer»

Liquids:

1. Viscosity increases with increase in density of the liquid. Viscosity increases with increase in pressure (except water).

2. Gases:

Viscosity decreases with increase in density. Viscosity decreases with increase in pressure.
