1. The problem statement, all variables and given/known data Compare the Internal (or Thermal) energies of the different containers sketched below. Choose the correct ranking of the internal energies provided. Each container contains H2 molecules with the shown amount (the number of molecules) at the same temperature. a) A=B=C=D b) A>B>C>D c) C>A>B>D d) D>B>A>C http://img293.imageshack.us/img293/999/physicspicsa4.jpg [Broken] 2. Relevant equations 3. The attempt at a solution I believe the answer is D, because D has a greater amount of molecules, then it gradually decreases.
