There is a rod that is split into two sections. The left side is copper with value of 390, temp of 100 degrees c and the length is 2m. The right side is silver, 420, temp 20 degrees celsuis, and length 1m.
I need to calculate the temperature.
390 X 1 X 100t / 2 = 420 X 1 X t20 / 1
Is this how I would set it up to solve for the temp?
Thank you.

What are your 390 and 420 "values" and what are their units?
What temperature are you solving for? is this supposed to be a steady state problem?

I believe that 390 is the coefficient of thermal conductivity "κ" from
dQ/dt = κ•A•dT/dx.
The units of "κ" are watts/K• meters. Its value for cooper is 390.
As for the rest I'm in complete accord with drwls: what temperature ....
