| - Do you think the movement of all particles is the same for all substances given the same energy? For example, should a particle of hydrogen (mass = 1.01 amu) move at the same velocity as a particle of nitrogen (mass = 14.01 amu) for a given temperature? | - Do you think the movement of all particles is the same for all substances given the same energy?
