But heat is random motion, in all directions.  It's the vector sum
of the momentum that is conserved, not a scalar sum, so all of that
heat momentum cancels out. Any of it that doesn't is observed as
macroscopic movement of an object, not heat.  So no matter how much
heat energy is absorbed, the net momentum change for the heat
vibration is zero.

Hmm, this is verging on off-topic for the list... : )
