    Agreed, the 6 mark question had very few space, so i ended up writing on the pink sheet... I got confused on the one with finding the frequency, i looked at the equation sheet and basically switched it around and got something like 120000, I can't remember exactly because i done a past paper before the exam and the same style question came up, so i might of mixed the answer with that

    that was strange because the u values for double glazing were higher meaning more energy transfer took place...what did you put?
    I put that the bigger the U value the better the insulator so the glass door is a better insulator ans something else

    i got somethining like 120000 for tht question too

    for the u value question about the wall and the window i wrote that the window had a higher u value then the wall so the wall is a better insulator because it keeps more heat energy in the house, and i wrote something about more energy is lost when they placed the window because of its high u value

    what did you lot write for that question?

    I thought it was the lower the U-Value the better it is at insulating??

    thats what i thought! i put that the double glazing transfers more energy!

    yeh i wrote the lower the u value the better the insulator and i just checked it in my revision guide its right

    Yes. I can't remember, I think I put however much higher it was in the U-Value and what that meant and then rambled on about some other stuff which probably won't get marks. I don't remember loads...

    I put that the efficiency stays the same because it was talking about weatehr which is unpredicatble!
    Yeah I put where the wasted energy goes is not how efficient the vehicle is

    How did everyone find it?!? The paper wasn't too hard I guess.. but, i think that grade boundaries will increase higher.. Everyone in my school were like.. "that was so easy" But, i really don't know, how i found it... there were some questions there that were pretty weird.. But, there wasn't anything like shocking .. it was pretty simple.. and i actually thought that the questions got easier towards the end LOL! Plus, I did have 10 minutes spare at the end which was good, got to check all my answers! But, why do guys reckon you would get?

    For the efficiency I put it increased as the energy transfer was heat energy and this is useful as the point of a radiator is to heat up the surroundings so less energy was wasted. But you guys all got something different so now I think I'm wrong :confused:

    I put that too- well I said that there is less wasted energy

    Yeh thats what I put, but other people said that the efficiency is the same. Do you or does anyone remeber what the question actually was?

    It was about the energy wasted form the engine heating the car. I put that it kept the efficiency the same because where the wasted energy goes isnt about the efficiency, but I think that the efficiency increased because it was usefully transferred by heat.
