i, ii and iii
Maelezo
The viscosity of a liquid depends on:
* Nature of the liquid: Different liquids have varying viscosities.
* Temperature of the liquid: Higher temperatures generally reduce viscosity.
The area of the liquid surface does not affect viscosity, it is an intrinsic property of the liquid.
