Cool water at 9.0°C enters a hot-water heater from which warm water at
temperature of 80 °C is drawn at an average rate of 0.3 kg min-¹ . How much
average electric power does the heater consume in order to provide hot
water at this rate? The specific heat capacity of water is given to be 4200Jkg-¹°C-¹
and assume that there is negligible heat loss to the surrounding

i would say the answer is food.
