Three liquids of densities $$\rho $$₁, $$\rho $$₂ and $$\rho $$₃ (with $$\rho $$₁ > $$\rho $$₂ > $$\rho $$₃), having the same value of surface tension T, rise to the same height in three identical capillaries. The angles of contact $$\theta $$₁, $$\theta $$₂ and $$\theta $$₃ obey

$${\pi \over 2} > {\theta _1} > {\theta _2} > {\theta _3} \ge 0$$

0 $$ \le $$ $$\theta $$₁ < $$\theta $$₂ < $$\theta $$₃ < $${\pi \over 2}$$

$${\pi \over 2} < {\theta _1} < {\theta _2} < {\theta _3} < \pi $$

$$\pi > {\theta _1} > {\theta _2} > {\theta _3} > {\pi \over 2}$$
