c) Assume the aluminum and copper rods (each with the length 20cm,diameter 4mm) are connected together with a joint of perfectthermal conductance. One end of the Cu is held at 0 C and one endof the Al is held at 50 C. Find the heat current through the rodand the temperature of the joint, T_joint.
Al: Density=2700kg/m^3 , Specific Heat c = 900J/kgK, thermalconductivity k=235 W/mK
Cu: Density=8900kg/m^3 , Specific Heat c = 392.2J/kgK, thermalconductivity k=401W/mK
