Homework Statement
The thermal conductivity of copper is 4 times that of brass.Two rods of copper and brass having same length and cross section are joined end to end. The free end of copper is at 0 degree C and the free end of brass is at 100 degree C. The temperature at the junction is?
Homework Equations
I don't know what equation to use.
R= r l/A?
Or thermal conductance = kl/A where k is the thermal conductivity?
Or is it something else?
