16. Consider the figure below. An electric stove having a rating of 3kW is use to boil a 6Li of tap water (Initially at 20°C and whose density at this temperature is 1020kg/m). If useful energy is around 62% of the total energy supplied by the stove. Determine how long would it take to vaporized all the water in the pan. 17. In previous problem, determine the total kW-hr used by the electric stove in the given condition.
