I Influence of electron's kinetic energy disspation during photoelectric emission

AI Thread Summary
The work function of a metal is influenced by its atomic structure and the binding energy of its outer electrons. Heavier alkali metals like potassium exhibit a low work function due to the weaker binding of their outer shell electrons. The discussion highlights the balance between the electromagnetic energy of the electrons and the dissipation of their kinetic energy during photoelectric emission. Ultimately, the properties of the metal's atoms play a crucial role in determining the work function. Understanding these factors is essential for applications in photoelectric devices.

What are the properties of a metal that determine its work function? What has a greater influence on its value: the electromagnetic energy of an electron (which is going to leave metal's volume because of photoelectric emission) and the atoms of the metal or the dissipation of electron's kinetic energy in the process of THIS electron leaving the volume of the metal?

I think the heavier alkali metals, such as Potassium, have a low work function, which I imagine is due to the loose binding of the electron in the outer shell?

Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
