A copper bar of thermal conductivity 401 W/(m · K) has one end at 104° C and the other end at 33° C. The length of the bar is 0.10 m and the cross sectional area is 1.0 10-6 m2.

(a) What is the rate of heat conduction along the bar?

___________ W

(b) What is the temperature gradient in the bar?

___________K/m

(c) If two such bars were placed in series (end to end) between the same temperature baths, what would be?

____________ W

(d) If two such bars were placed in parallel (side by side) with the ends in the same temperature baths, what would be?

_____________ W

(e) In the series case, what is the temperature at the junction where the bars meet?

_____________ ° C
