Answer Posted / neeraj batra
because thermal energy of valence electrons is zero, so they
can't move as they are bound with the atoms, however with
very low binding energy which can be supplied by little
thermal energy (temperature). So due to increase in number
of free electrons with increase in temperature, the
conductivity increases.
