Hey anyone knows which common materials get the warmest for heat absorption?

Diamond is the best heat conductor followed by metals--silver being the best but the less expensive copper is used more frequently. Then come quartz and glass followed by wood, styrofoam, wool, siilica aerogel, air, water, ice, and mercury--another metal which is somehow not a very good heat conductor.

Pots are fitted with copper bottoms because copper is a good conductor while the rest of the pot can be made of stainless steel-a mediocre heat conductor which will make the transfer of heat from the food in the pan and into the atmosphere slower.

Write an experiment on heat conductivity?
