QUESTION 10
A bar of gold (Au) is in thermal contact with a bar of silver (Ag) of the same length and area
(see figure below). One end of the compound bar is maintained at T= 119 C and the
opposite end is at 0.2 C. When the energy transfer reaches steady state, what is
the temperature at the junction (in °C)? The thermal conductivity of gold is 314 and silver is 427 (W/m. ° C).
