Question
Calculate the contact angle $\theta$ for olive oil if capillary action raises it to a height of 7.07 cm in a glass tube with a radius of 0.100 mm. Is this value consistent with that for most organic liquids?
$5.1^\circ$
Most organic fluids have a contact angle with glass of $0^\circ$. The value calculated here is fairly close to zero, and somewhat consistent with the expectation of $0^\circ$.
