Explain what determines the viscosity of a liquid?

Answer 1

the shape and size of the molecules that the fluid consists of, if they are big, wavy molecules then the liquid will be viscous because the molecules struggle to move over each other.

Answer 2

Viscosity of a liquid is determined by the intermolecular forces between its molecules. Strong intermolecular forces lead to higher viscosity, as molecules resist sliding past each other. Temperature also affects viscosity, with higher temperatures decreasing viscosity by increasing molecular motion.

Answer 3

shape of molecules

Answer 4

silica content
