Question:

(a) An immersion heater utilizing 120 V can raise the temperature of a 1.00 × 10²-g aluminum cup containing 350 g of water from 20.0°C to 95.0°C in 2.00 min. Find its resistance, assuming it is constant during the process.

(b) A lower resistance would shorten the heating time. Discuss the practical limits to speeding the heating by lowering the resistance.
