8. A copper bar of thermal conductivity 401 W/(m·K) has one end at 117°C and the other end at 24.0°C. The length of the bar is 0.120 m, and the cross-sectional area is 1.00 × 10−6 m2. If two such bars were placed in series (end to end) between the same constant-temperature baths, what would the rate of heat conduction  PP be?
