Is concrete a good conductor of heat? - S.N Goh (age 10) Singapore
A:
Not particularly. Metals in general are very good conductors, silver being tops. Concrete conducts heat only about 1/500 the rate of silver. For a good list of the conductivities of various materials, see http://hyperphysics.phy-astr.gsu.edu/hbase/tables/thrcn.html
