To help keep her barn warm on cold days, a farmer stores 865kg of warm water. How many hours would a 2.00-kilowatt electric heater have to operate to provide the same amount of heat as is given off by the water as it cools from 20.0 degrees celcius to 0.0 degrees celcius and then freezes at 0.0 degrees celcius?
