Heating bodies

  1. Oct 31, 2014 #1
    Suppose the following experience:
    Two identical cans one black and one white with equal mass of water inside.
    We focus radiation at the same power on each.
    After enough time, that we want, do the water will reach the same temperature in both cans?
    If not, can we conclude that the water was at different temperatures in the cans at the begining of the experiment?

    Please explain what you mean by this.

    Suppose that the water in the black can goes to 50 ºC. Is it possible that the water in the white can goes to 50ºC, if we gave it enough time, maintaining same initial conditions?
