Problem 2: An insulated tank contains 0.15 kg of liquid water and has a 0.25-kg copper base. The thin walls of the container have negligible mass. Initially, the tank and its contents including the copper base are all at 30°C. A heating element embedded in the copper base is energized with an electrical current of 10 amps at 12 volts for 100 seconds.Determine the final temperature, in °C, of the tank and its contents. Take specific heat data from problem 1. Hint:For electrical work/power information, consult the handout “L4_Chapter 4_Supplementary information_types of work and power formula”, uploaded in Canvas. Use energy balance equation and proceed accordingly as problem 1.
