Question 11

On a cold winter day, a metal gate post $A\,$ and a wooden fence post $B\,$ are at the same physical temperature, which is below human body temperature.

Why does the metal post $A\,$ feel much colder to the touch than the wooden post $B$ ?

$A$ is a better thermal insulator than $B$ .

$A$ is a better thermal conductor than $B$ .

$A$ has a lower thermal capacity than $B$ .

$A$ is a better radiator of infrared radiation than $B$ .
