Find the minimum ampere rating of an electric heating system

Reference no: EM13289607

To save on heating costs, the owner of a greenhouse keeps 580 kg of water around in barrels. During a winter day, the water is heated by the sun to 9.5° C. During the night the water freezes into ice at 0.0° C in 9 hours. What is the minimum ampere rating of an electric heating system (120 V) that would provide the same heating effect as the water does?
