Problem
A brass block of mass 150 g and specific heat 0.38 J/g·°C is pressed firmly against one end of a steel rod whose other end is maintained at 180 °C. While the temperature difference across the rod stays constant, thermal energy enters the block at a steady rate of 12 W. Determine the initial rate, in °C/s, at which the temperature of the brass block increases.
