okay thanks. I am still a little bit confused. thanks for the help. :)

I got it... I looked it up on google. The way they solved it... T(junction) = T2 + (T1-T2)*kCu/(kCu+kFe) = 0 + (100-0)*400/(400+80) = 83.33 C Its the correct answer... if the copper was at 100 C. (my problem was a different version) would you please explain to me how they set up the...

Dadface OKay so the k for copper is 400W/mK and for Iron it is 80W/mk I am sorry, but I honestly don't understand it. Obviously the units m will cancel out, including the units K. So you are left with W. Thats all I could figure out. I am really lost. I am looking at my book, and there's a...

How do you approch this problem. I have the same one. I thought you could use specific heat also. Guess not. You can't use the equation Q/Change T = K(A/L)*change in T because since our length is zero, it would cancel everything else. And it doesn't even provide the area. Please help
