…………. is a good conductor of heat and electricity?

Graphite is a good conductor of heat and electricity.

Explanation:

i. In graphite, carbon atoms are arranged in different layers.

ii. In each layer, every carbon atom is linked to three neighboring carbon atoms.

iii. Thus, the fourth electron of each carbon atom is free to move continuously within the entire layer.

iv. Because of the presence of these free electrons in different layers, graphite becomes a good conductor of heat and electricity.
