Determine the minimum power rating of this heater

Reference no: EM13339885

0.25 kg coffee mug is made from a material that has a specific heat capacity of 990 J/(kg°C) and contains 0.31 kg of water. The cup and water are at 25°C. To make a cup of coffee, a small electric heater is immersed in the water and brings it to a boil in two minutes. Assume that the cup and water always have the same temperature and determine the minimum power rating of this heater.
