Average velocity of the particles if there are enough of them to collide frequently (and if you can factor out bulk motion). But you can also look at average vibrational energy.

    So collisions would provide enough energy to call them hot, or is that a term of art, like calling all non-hydrogen, non-helium elements "metallic"?
