    From jan 2013:

    Nuclear fission can lead to a chain reaction by:

    -Nucleus splits.
    -Releases nuclei.
    -Which are absorbed by different nuclei.

    This process releases energy in the form of kinetic energy of the products.

    Pressurised water acts a coolant.

    Moderator slows down the neutrons.


    Energy transfers in a power station:

    Heat energy is released by a moderator >>> Thermal energy in water/steam >>> Kinetic energy in generator >>> Electrical energy in wires.

    good

    there were 2 q about efficncy right ?

    i got for first one 899 you ?

    and the second 899 divided by 72 then x 100 i got 1280 something like that and you ?

    I got 899 too.

    The second was to divide by 0.72 but I did get a value like that.

    didnt obey.

    But you could have said it did.

    I said gradient not constant, gradient not a straight line, tested 2 points out from load and unload to show that k was not constant/equal.

    Idk because it never went past its breaking limit.

    I thought it was a bit ****!! It was alright but some of the questions were conditional, like when it said about how far the planets could be away fro each other, but didn't tell you the diameter of the star so yeah it was alright but little things like that thre me off I found chemistry a lot better

    The greatest distance was the sum.

    The smallest distance was the difference.

    I found chem a lot harder personally.

    Nice comet question, which I had done the night before
