The correct answer is D. Viscosity of liquids is appreciably affected by change in pressure.
Viscosity is a measure of a fluid’s resistance to flow. It is due primarily to the interaction between fluid molecules. The higher the viscosity, the more resistance there is to flow.
The viscosity of liquids decreases with increasing temperature. This is because the molecules in a liquid move faster at higher temperatures, and they are therefore less likely to interact with each other.
The viscosity of liquids is not appreciably affected by change in pressure. This is because the pressure does not change the distance between the molecules in a liquid, and it therefore does not affect the strength of the intermolecular forces.
In conclusion, the correct answer is D. Viscosity of liquids is appreciably affected by change in pressure.
