Distinguish between specific bent and thermal conductivity or a substance.

Explanation

Specific heat of a substance corresponds to the amount of heat required to raise 1 kg of the substance through 1K of temperarture. It is expressed in terms of `Jkg^(-1)K^(-1)`
Thermal conductivity refers to the heat conduction during the steady state. Thermal conductivity expressed in terms of `Wm^(-1)K^(-1)`
e.g Specific heat of water is 4200 `Jkg^(-1)K^(-1)` and thermal conductivity of water is `0.8Wm^(-1)K^(-1)`
Thus 1 kg of water requires 4200J of heat to raise the temperature by 1K. In thermal conduction, 0.81 of heat will be conducted by water having a unit area of cross section and 1K of temperature difference between the two layers of water separated by 1m apart.
