Temperature and Movement

  1. Jan 21, 2016 #1
    Hey guys,

    I have been wondering about this for a long time, and I can't seem to reach a solid conclusion. If temperature of an object is related to the movement of its atoms, then is it true to say that a moving object have a higher temperature?

    Atoms in hotter objects have more highly excited electrons.
    That is intrinsic to the object, it's not dependent on whether the object is at rest or is moving in relation to any other object.

    Temperature is an emergent effect of random motion of the particles in the system.
    It is usually defined as what a thermometer stationary wrt the thing being measured will read.

    Note: the particles in a hot (monotonic ideal) gas will have higher rms velocity than in a cooler gas.
    More complicated systems will divide the energy up in more different ways, i.e. mostly as motion in electrons in a solid.
