Description
Short description
"In this experiment, we observe mercury inside a container. We can see that it does not extend along its edges, but rather forms a fairly thick side.
If we start the experiment, the bar hits the mercury, which disintegrates into small spheres that maintain their shape, until they quickly regroup when they come into contact with the rest of the mercury.
Why does this happen? This happens because of high surface tension. This surface tension is the result of the great attraction that mercury molecules exert on each other. The molecules located on the surface of the liquid are strongly attracted by those inside so that, if it is divided into small quantities, the mercury takes the form of a small ball. Only when the size of the ball of mercury is increased, its weight becomes greater than the surface tension and, consequently, its shape breaks apart."
