A tin calorimeter cup with a specific heat of 210 J/(kg · °C)contains kerosene with a specific heat of 2,018 J/(kg · °C) at 16.0°C. The combination is heated uniformly so that the temperature changes by 1.30°C per minute. If the cup has a mass of 200 g and contains 900 g of the liquid, determine the rate at which heat energy is added (in W).
