Heat Exchange

  1. Nov 13, 2008 #1
    1. The problem statement, all variables and given/known data

    Two containers contain molecules at different temperatures as shown. They are allowed to exchange heat between them, but not with outside. Which of the following statements is most accurate?

    a) Container #1 looses Internal energy, container #2 gains internal energy
    b) Container #2 looses Internal energy, container #1 gains internal energy
    c) Heat flows form container #1 to container #2
    d) Heat flows from container #2 to container #1
    e) Both a and b are true
    f) Both b and c are true
    g) Both b and d are true

    2. Relevant equations



    3. The attempt at a solution

    G? Due to diffusion because the molecules are moving from an area of high concentration to an area of low concentration.

    I'm still really confused about this one. Any help would be appreciated.

    The molecules appear to be sealed off in their own respective containers, so I don't see how they could diffuse from one into the other.

    The initial temperatures of the two containers are given, so one is clearly hotter than the other. That's enough information to figure out which way heat flows.
