Conduction carries heat through a solid as vibrating particles jostle their neighbours, and in metals a sea of free electrons sweeps the energy along far faster. A good conductor like copper moves heat to the cold end in moments, while an insulator like wood barely passes it at all. Choose a material that delivers heat to the far end inside the time limit.
