An office worker uses an immersion heater to warm 250 g of water in a light, covered, insulated cup from 20.C to 100. C in 4.00 minutes. The heater is a Nichrome resistance wire connected to a 120-V power supply. Assume the wire is at 100. C throughout the 4.00-min time interval. (a) Calculate the average power required to warm the water to 100. C in 4.00 min. (b) Calculate the required resistance in the heating element at 100. C. (c) Calculate the resistance of the heating element at 20. C. (d) Derive a relationship between the diameter of the wire, the resistivity at 20. C, 0, the resistance at 20. C, R0, and the length L. (e) If L = 3.00 m, what is the diameter of the wire?
