Two metal rods, one silver and the other gold, are attached to each other
The free end of the silver rod is connected to a steam chamber, with a temperature of 100°C, and the free end of the gold rod to an ice water bath, with a temperature of 0°C. The rods are 5.0 cm long and have a square cross-section, 2.0 cm on a side. What is the temperature at the point where the two rods are in contact with one another? The thermal conductivity of silver is 417 W/(m•K) and that of gold is 291 W/(m•K) No heat is exchanged between the rods and the surroundings, except at the ends. A) 39°C
B) 41°C
C) 47°C
D) 53°C
E) 59°C
