The viscosity of a liquid is a measure of its?

Resistance to flow
Rate of change
Weight or density
Color change

The correct answer is: Resistance to flow

Viscosity is a physical property of a fluid that describes its resistance to flow. Higher viscosity means the fluid is thicker and will flow slower, while lower viscosity means the fluid is thinner and will flow faster. Option B, rate of change, is not related to viscosity and is usually used in mathematical or scientific contexts. Option C, weight or density, can contribute to a liquid's viscosity, but alone it is not a measure of it. Option D, color change, has no relation to viscosity whatsoever. Therefore, A is the correct answer as it accurately describes the property being measured.
