    A solar panel attached to the roof of a house is used to heat water from 5 degrees to 45 degrees.
    If the water flows through the panel at a rate of 0.012kg/s, calculate the heat gained per second by the water. Assume the specific heat capacity of water is 4200 J/kg/K.

    Using the formula energy transferred=mass*specific heat capacity*temperature change

    E/t=(0.012*4200*40)/t where E is energy (in this case thermal, and t is time)

    But here t=1 second so E/1 = (0.012*4200*40)/1=2016J/s (also meaning the power of the solar panel is 2016W)
