Question

is it necessary that the materials who are good conductors of electricity would also be good conductor of heat like GRAPHITE ? please help

Answer 1

Thats a great question, even i have wondered about that, i think YES.. let an expert answer this now!

Answer 2

no i think that not is right what you have wrote there

Answer 3

i meant that since graphite is a good conductor of heat and electricity in general use
but why is it so that just because of free electrons present in it it is both conductor of heat and electricity

Answer 4

yes is right

Answer 5

how ? does free electrons also affect the conductance of the material of heat

Answer 6

Mr Kusha please help me with my math question he posted on the wrong subject!

Answer 7

Answer 11

for conducting electricity we need free electrons
in the case of heat the electrons vibrate more & more as heat is supplied.
they transfer this vibrational energy to electrons of adjacent atoms causing transfer of heat .
For this too u need the electron to be a little loosely bound
so generally good conductors of heat are good condutors of electricity
But there are exceptions
