Two rods, one of aluminum and the other of copper, are joinedend to end. The cross-sectional area of each is 4.0 X 10^-4meters squared, and the length of each is 0.040 m. The freeend of the aluminum rod is kept at 302 degrees C, while the freeend of the copper rod is kept at 25 degrees C. The loss ofheat through the sides of the rods may be ignored.
(a) What is the temperature of the aluminium copper interface?
(b) How much heat is conducted through the unit in 2.0seconds?
(c) What is the temperature in the aluminiumrod at a distance of 0.015 meters from the hot end?
