Water Properties (continued)


Superficial tension

Another feature of liquid water is the tension it represents on its surface. This is because water molecules attract each other, keeping together (together), as if they formed a very thin surface membrane. Look at the picture below.

Pascal's principle

Pascal was a French scientist who lived from 1623 to 1662. Among many collaborations with science, he formulated the following principle: "The pressure exerted on a liquid is transmitted integrally to all points of the liquid." Look at the picture below:

When we strongly push a cork into a bottle containing liquid, this pressure is transmitted entirely to the liquid in the container. The water pressure inside the bottle increases and pushes the other cork out.
