That's correct.  Any kind of atomic (including electronic) activity is
directly affected by heat.  I think I'm right in saying that the
application of heat to a system is the *only* way to increase an atomic or
subatomic particle's energy.  This includes electrons.  Another poster was
correct in that the hotter the system, the greater the resistance, too.
(If you're a copper atom and get really hot, you're going to be moving
around a lot more.  So are all your neighbors.  It's a lot harder for an
electron to get past you and your buddies when this happens.  That's why
the resistance goes up.)

Therefore, we have a bit of a complex system.  You have to determine how
much the resistance is going to rise as the temperature goes up.  Then you
have to figure out how much more active the electrons are going to be with
that same increase in temperature.  Then, determine which has more effect
on the system.  When you get all that figured out, lemme know what you come
up with!  :)
