Question

Assume that the thermal conductivity of copper is twice that of aluminimum and four times that of brass Three metal rods made of copper aluminium and brass are each 15 cm long and 2 cm in diameter These rods are placed end to end with aluminium between the other two The free ends of the copper and brass rods are maintained at 100 C and 0 C respectively The system is allowed to reach the steady state condition Assume there is no loss of heat anywhere then More heat is transmitted across the copper aluminium junction than across the aluminium junction brass Equal amount of heat is transmitted at the copper aluminium and aluminium brass junctions Under steady state condition the equilibrium temperature of the copper aluminium junction will be 85 71 C
