(a) A well-insulated electric water heater warms 121 kg of water from 20.0*C to 43.0"C in 35.0 min. Find the resistance (in () of its heating element, which 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 43.0"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
