(a) A well-insulated electric water heater warms 127 kg of water from 20.0°C to 45.0°C in 23.0 min. Find the resistance (in 0) of its heating element, which is connected across a 240 V potential difference. (b) What If? How much additional time (in min) would it take the heater to raise the temperature of the water from 45.0°C to 100°C? min (c) What would be the total amount of time (in min) required to evaporate all of the water in the heater starting from 20.0°C? min
