Question:

The stem of a glass hydrometer used to measure specific gravity is \(5 \mathrm{~mm}\) in diameter. The distance between marks on the stem is \(2 \mathrm{~mm}\) per 0.1 increment of specific gravity. Calculate the magnitude and direction of the error introduced by surface tension if the hydrometer floats in kerosene. (Assume the contact angle between kerosene and glass is \(0^{\circ}\).)
