How does heat conductivity work? Al -> Cu

[hlock]

TL;DR

Will copper draw heat out of aluminium to be hotter then the Al?

One has two same volume blocks of metal, one Aluminium and one copper pushed together. If the Aluminium is instantly heated to 100 degrees C, since it has significantly higher heat conductivity will the copper draw the heat out and at some point be hotter then the aluminium? Or will it just draw the heat out until it hits equal temperature?

See Clausius' statement of the second law of thermodynamics.

Ok thankyou, "Heat can never pass from a colder to a warmer body without some other change" so essentially it will equalise. Though I assume heat transfer Al->Cu will keep happening as the Cu will shed it faster.

What is the exact situation you are looking at? Your present description is rather confusing?

the Cu will shed it faster.

i am not sure what you mean by the statement

i am not sure what you mean by the statement

I assume he means the Cu radiates/conducts it into the environment faster than the Al will.

But does it?
