What is the sum of kinetic energy of atoms or molecules

Question

I just need my question answered 

Answer 1

What have you tried to do to approach the solution?

Answer 2

This is a strange question.  If you add up all the kinetic energies of the atoms or molecules of a system, you will have the total kinetic energy of the system.  I think some other question was intended here. Perhaps the question is asking about thermal energy?
