Specific heat capacity of substance A is 3.8J/g/k whereas the specific heat capacity of substance is 0.4J/g/k ?) which is the good conductor of heat ?) How is oneled tot he above conclusion Share with your friends Share 0 Tejan Gupta answered this Dear student,i) substance B is a good conductor of heat.As the less specific heat of a substance means the better it acts as a good conductor.Less specific heat means it takes little time for teh heat transfer.ii) As the specific heat of B is less than that of A, so B is a good conductorRegards 1 View Full Answer
