An electric heater is used to heat up 3.00× 102 kg of water from 10.0°C to 80.0°C in twenty minutes. Assuming that the heater is connected to a 120-V (rms) source and all electric power is used to heat the water, what is the resistance of the coil in the heater? The specific heat of water is 4186 J/(kg K).
