On which of the following factor does the viscosity of a liquid depend? i. Nature of the liquid. ii. Temperature of the liquid. iii. Area of the liquid surface
A
i and ii only
B
ii and iii only
C
i and iii only
D
i, ii and iii
Verified Correct Answer: A.
Physical Principles & Numerical Solution
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.
