Question
A 0.253-kg coffee mug is made from a
material that has a specific heat capacity of
944 J/kg C° and contains 0.277 kg of water.
The cup and water are at 20.6 °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.
