Hey there guys. This is my attempt at creating a (hopefully correct) bank of solution for the GCSE AQA P1 paper sat by a lot of us today.
Just a couple of things to clarify:
I don't do requests. Don't bother wasting your time.
No one's saying these are 100% correct, they're just what I've seen to be true and what I thought was right. If there's any problems you can spot, feel free to quote me in on them
These are by no means the only correct (assuming they are even correct
) answers. If you think there are alternative correct solutions, just quote me and I'll edit them in.
Now we've got all that out of the way, here we go!
P.S. If anyone starts a massive argument about a 1 mark question, I will track you down and slit your throat with a rusty spoon, srs. k?
P.P.S Just in case anyone was feeling the need to post 'for the sake of it' corrections, please just do me a favour and **** off now.

2) This was on solids and gases, not liquids.
4) a) i) I'm sure it doesn't mean that but means a 440 wavelengths pass a particular point in one second.
8) a) i) and a) ii) I'm certain it was 5.8 watts as useful energy, and subsequently wasted energy was 8.2 watts.
8) b) ii) Should say 'line graph' because the variable was continuous as opposed to categoric, at which point it would be a bar chart.

8aii) 14W - 5.9W = 8.1W
8b) LED bulbs have a greater efficiency than halogen bulbs, so more of the total power is used for light. In addition to this, they also have a significantly lower input power (7W compared to 40W) than the halogen lamp, which means that less energy will be required per second and therefore less money will be spent on electricity.

For 8b) the question asked something in relation to why the cabinet being less effective if LED were to replace halogen bulb (might be wrong here but unsure).

Did 4aii ask for 3sf because I rounded to 2dp and got 0.77, would I lose any marks?

Thanks.
Will i get any marks for saying: scatter graph (with line of best fit) instead of line graph?
They do the same job.

Yes that question confused me
does anyone know whether nuclear energy is a more concentrated Source than gas for the first question. Also for the scientist one could you just say that people will have different opinions or something along those lines?
