Any substance with a defined set of physical properties that can transmit energy

The answer to this question is conductor.

The substance contains different physical properties are the transfer of energy, conductivity, density, melting and freezing etc. Any object that can transfer the energy in the form of heat or electrical conductivity can be called as conductors. It is the property of conductors to transfer the energy of heat from one side to another side of the object. The conductors have the follows the rule of the conduction process to perform this specific function.

So, the right answer to this question is the conductor.
