What is the electrical and thermal conductivity of graphite?

A solid with high electrical and thermal conductivity from the following is

Compare the structure of the crystal of diamond graphite with special reference to the reason for diamond being the hardest natural substance while graphite one of the softest. Compare the electrical & thermal conductivity of the two crystalline allotropes of carbon.

A thermal conductor is heated at one end. What is the theoretical value of its thermal conductivity in order that the other end also attains the same temperature?

The thermal conductivity of a rod depends on

The thermal conductivity of a rod depends on

The thermal conductivity of a rod depends on

The unit of thermal conductivity is :

The unit of thermal conductivity is :

IF two metallic plates of equal thickness and thermal conductivities K_(1) and K_(2) are put together face to face anda common plate is constructed, then the equivalent thermal conductivity of this plate will be

Statement I: Two solid cylindrical rods of identical size and different thermal conductivity K_1 and K_2 are connected in series. Then the equivalent thermal conductivity of two rods system is less than that value of thermal conductivity of either rod. Statement II: For two cylindrical rods of identical size and different thermal conductivity K_1 and K_2 connected in series, the equivalent thermal conductivity K is given by (2)/(K)=(1)/(K_1)+(1)/(K_2)
