Answer: The capillary rise(h) in the glass tube is = 0.009m

Explanation:

Using the equation

h = 2Tcosθ/rpg

Given

Contact angle, θ = Zero

h = height of the glass tube=?

T = surface tension = 0.032J/m^2

r = radius of the tube = 0.1mm =0.0001m

p= density of ethanol = 0.71g/cm^3

g= 9.8m/s^2

h = (2 * 0.032 * cos 0)/( 710*9.8*0.0001)

h= 0.09m

Therefore the capillary rise in the tube is 0.09m
