A metal rod is placed between two temperature sources so that heat can flow between them. One temperature is 90.0 °C and the other temperature is 25.0 °C. The length of the rod is 30.0 cm and the cross-sectional area is 10.0 cm2. If 15.0 watts of heat flows between the hot temperature and the cold temperature, then what is the thermal conductivity for the metal?



69.2 W/(m·°C)



58.2 W/(m·°C)



50.4 W/(m·°C)



46.3 W/(m·°C)



44.2 W/(m·°C)
