Homework Help: The average translational kinetic energy of nitrogen molecule

  1. Apr 21, 2010 #1
    1. The average translational kinetic energy of a nitrogen molecule at temperature is _____

    check picture


    3. The attempt at a solution:
    since nitrogen is diatomic then it has 5 degrees of freedom and therefore the average kinetic energy wouldnt be 3/2kt it would rather be 5/2kt and therefore E=1*10^-20

    Yes but translational energy would still be 3/2kT.
