Homework Help: Thermodynamics equation and kinetic theory

  1. Sep 18, 2012 #1
    kinetic theory

    1. The problem statement, all variables and given/known data
    Hi all, I have 1 question that I hope to clarify:

    Regarding the kinetic theory: it states, that the kinetic energy of ideal gas is 3/2KBT.

    However, it is stated in my textbook and other sites that kinetic energy of ideal gas is 3/2nRT. The 2 equations look very similar in nature, so what is the difference? Because KB≠nR (or whatever variables in the equation?)

    Thank you!

    2. Relevant equations

    3. The attempt at a solution
