A brass rod with a length of 20.0 cm is placed side by side with an aluminum rod with a length of 20.0 cm and this system is placed between a hot temperature of 150 degrees Celsius and a cold temperature of -10.0 degrees Celsius. The coefficient of thermal conductivities of the brass and the aluminum are 100 W/m degrees Celsius and 230 W/m degrees Celsius respectively. The rods have the same cross sectional area of 20.0 cm^2. What is the heat flow from the hot temperature to the cold temperature?
