A thin bar composed of aluminum is 20 cm long. It is initially at a uniform temperature of 30° C. At time t = 0, the left end of the bar (x = 0) is placed in a bath at a constant temperature of 20° C. The right end of the bar (x = 20 cm) is placed in a bath kept at a constant 40° C. (a) Derive the temperature function of the bar for any point in the bar at any time. How does the temperature at the center of the bar change with time?
