Homework Help: The potential energy of the molecules

  1. Apr 20, 2010 #1
    1. The problem statement, all variables and given/known data

    What is the potential energy between the atoms in a body?
    Its a huge exercise, so Im not going to type the whole thing, but this is where I got stuck.

    2. Relevant equations

    You tell me.

    3. The attempt at a solution

    I found out what the temperature of the body was, and then I found out what the kinetic enery of a single atom was. Now I knew how many atoms there were so I could easily find the kinetic enery of all the atoms, but how can I find the potential energy of the atoms?

    Thanks in advance,

    in your problem, you'll need electrostatic potentials (gravitational is too weak to have any significant effect), or Coulombs potential. so check out what atoms or molecules your problem is asking for, count their electrons and protons, and find their net interaction by using coulombs law.
    this is what i got from your question so i hope this helped.
