A copper rod 83.0 cm long and with a diameter of 1.3 cm is used to poke a fire. The hot end of the rod is maintained at 103.0 oC and the cool end has a constant temperature of 21.0 oC. The thermal conductivity of copper is 395 W/(mK).

1) What is the rate of the heat flow through the rod?

Q/t =

2) What is the rate of the heat flow between the cold end of the rod and a point 24.0 cm away from it?
