A brass rod with a length of 30.0 cm is placed side by side with an aluminum rod with a length of 30.0 cm, and this system is placed between a hot temperature of 100°C and a cold temperature of 10.0°C. The thermal conductivities of the brass and the aluminum are 100 W/m °C and 230 W/m °C, respectively. The brass rod has a cross-sectional area of 20.0 cm2, and the aluminum rod has a cross-sectional area of 30.0 cm2. What is the rate of heat flow from the hot temperature to the cold temperature?
