GEOLOGY

Detailed explanation-1: -So the given statement is true.

Detailed explanation-2: -Viscosity is a measure of a fluid’s resistance to flow. A fluidwith large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion.

Detailed explanation-3: -(b) Viscosity is not a property of gases.

Detailed explanation-4: -For gases, viscosity increases with temperature but is independent of pressure whereas for liquids, viscosity increases with pressure.

Detailed explanation-5: -The property of a fluid due to which it opposes the relative motion between its different layers is called viscosity (or fluid friction or internal friction) and the force between the layers opposing the relative motion is called viscous force. It is caused by intermolecular forces and momentum transfer.
