Question

name the best conductor of heat? and also second best conductor of haet

Answer 1

To my knowledge, silver is the best conductor of both heat and electricity among metals with a thermal conduction value of about 430 W/(mK). Gold and copper both come respectably close to silver, and with Copper being significantly less costly it is often chosen over silver in many applications..

second best conductor is Copper is a good conductor of heat. This means that if you heat one end of a piece of copper, the other end will quickly reach the same temperature. Most metals are pretty good conductors; however, apart from silver,copper is the best.

Answer 2

gold ,sliver,aluminum,,iron,copperare good conductor
silver is the best conductor of both heat and electrical among the
metal with a thermal conduction value of about 430 w/(mk).gold and copper both come respectively close to silver,and with copper being significantly less costly it is often chosen over silver in many application,however,t hats just among metals .diamond is actually a mush better heat conductor than silver,
around5 diamond times better than for an average diamond . scientist have also made super pure diamond that can easily be up to 5 times better than regular diamond
