Internal Energy

  1. Nov 12, 2008 #1
    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

    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.

    Sure...the question tries to make you realize whether internal energy is an intensive or an extensive quantity: have you had those concepts?

    I just want to make sure... D is the correct answer?

    Yes. Why the doubt?
