A pot containing 2 liters of 5 celsius water is putt on a stove that is 1500 watts. Now the stove is on. How long time will it take for all of the water to boil from the pot? (turn into vapour). No heat is lost to the surroundings.

Answer 1

a liter of water is a kilogram

1500 t = Joules in if t is seconds

1500 t = specific heat water * 2 kg *(100-5)degrees K + heat of vaporization* 2 kg
