Which heats up more quickly, iron or copper?

(300 K) 80.4 W·m−1·K−1=Iron
(300 K) 401 W·m−1·K−1=Copper
I found these answers on Wikipedia (online dictionary).
I would go with copper. I am wondering since there is 300k if this is a trick question and the answer is "they both heat up at the same rate."

To determine this, you'd want to look at the specific heat capacities of the two metals. The metal with the lower specific heat capacity will heat up more quickly (because it requires less energy to heat up the same mass of metal).
Looking at a nearby gen chem textbook, iron's specific heat capacity is 0.451 J/g C while copper's is 0.385 J/g C. (These numbers will vary a little depending on their source.) Since copper has the lower heat capacity, it will heat up more quickly than iron.

iron, because ive heard Copper or aluminum cookware won't heat up at all
