EuPhO 2026, experiment — Задача 5. Task E5: Surface tension (2.5 pts)

Experimental task Language: English · 2,5 т.

Условие

The shape of the droplet depends only on its volume $V$ and the ratio $P^2/\sigma$. Here, $\sigma$ is the surface tension of the liquid.

a) Perform a measurement to find out which liquid, I or II, has a lower surface tension. (0.5 pts) [0,5 т.]

b) Experimentally determine the surface tension of liquid I, given that the surface tension of liquid II is $0.073\ \mathrm{N/m}$. (2.0 pts) [2 т.]
