    1. The problem statement, all variables and given/known data
    A stove burner supplies heat to a pan at the rate of 1500 W. How
    long will it take to boil away 1.1 kg of water, once the water
    reaches its boiling point?


    2. Relevant equations
    q = mct


    3. The attempt at a solution

    heat transfer = 1500 W, m = 1.1 KG Tf = 100

    Look up latent "heat of water". That will allow you to calculate the amount of energy needed to turn 1.1kg of water at 100C into steam at 100C.

    Then remember the equation that relates Power, Energy and Time.
