Answer:
motor oil
Explanation:
According to Oxford dictionary, viscosity refers to ''a quantity expressing the magnitude of internal friction in a fluid, as measured by the force per unit area resisting uniform flow.''
The higher the molecular weight of a substance, the greater its viscosity. This is because, the long chains in the viscous substance become entangled thereby increasing the internal friction in the liquid.
Motor oil is a heavier hydrocarbon than gasoline hence it is more viscous than gasoline.
