Random versus ordered combustion temperature

  1. Feb 19, 2010 #1
    1. The problem statement, all variables and given/known data:
    Molecules in the combustion chamber of a rocket engine are in a high state of random motion. When the molecules leave through a nozzle in a more ordered state, will their temperature be more, less, or the same as their temperature in the chamber before being exhausted?

    2. Relevant equations temperature (energy) rises(or falls) as pressure increases (or decreases)

    3. The attempt at a solution
    temperature is more leaving through the nozzle, in a more ordered state (???)
