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)
