Specific heat...

Question

Specific heat capacity of a substance A is 3.8 J $g^{- 1} K^{- 1}$ and of the substance B is 0.4 J $g^{- 1} K^{- 1}$ .Which substance is a good conductor of heat? How did you arrive at your conclusion ?

Open in App

Solution

Substance B is a good conductor of heat. Less is the specific heat capacity of a substance, the better it acts as a good conductor. Less specific heat means it takes little heat for heat transfer.
