Rise of oil a wick is due to

A. Density of the oil

B. Viscosity of the oil

C. Surface tension of the oil

D. Pressure of the oil

Answer: Option C

Solution (By Examveda Team)

The phenomenon of rise or fall of liquid in a capillary tube is called capillarity. Oil rises through a wick due to capillarity. The narrow pores in the threads of a wick act like tiny capillaries, through which oil rises. Capillary action is the result of adhesion and surface tension.
