Which statement about thermal conduction is not correct?
It is the primary method of thermal energy transfer in solids.
It occurs when particles with more kinetic energy collide with neighboring particles to transfer energy.
It is much faster in metals due to the presence of free, delocalized electrons.
It involves the bulk movement of the heated substance from one place to another.
