What is stronger – Water or an Air?

by darinapoljak

On September 24th 2016 there was one unusual lesson from physics. The theme was the pressure of the static fluid. In fact, in introduction, we were talking about the pressure on the bottom of the ocean, what is the hydrostatic pressure, atmospheric pressure..

After the introductory part, we moved into the schoolyard. We had a little play with the water, wanting to know what would happen if a cup full of water cover and turn it upside down ..

The students were given their assumptions – some thought that the pressure of the water is stronger and it will blow immediately… They started to cheer – for water and for air.. or maybe they are equal?

Also we concluded that the pressure exerted by a static fluid depends only upon

  • the depth (height) of the fluid
  • the density of the fluid and
  • the acceleration of gravity.
