<font size="5">As you've seen, when an atom is excited by a collision with
another atom, it moves more slowly after the collision than it would
otherwise. The reason for this is simple: <b>it takes energy to excite an
atom. </b>That energy has to come from somewhere and in this case it comes
from the <b>kinetic energy </b>of the atoms. </font>
