A brass rod with a length of 10.0 cm is placed end to end 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 coefficient of thermal conductivities of the brass and the aluminum are 100 W/m °C and 230 W/m °C respectively. The rods have the same cross sectional area of 20.0 cm2. What is the heat flow from the hot temperature to the cold temperature?
