AQA GCSE Physics P1 12/06/2014

Hi. :smile: The P1 exam is on Thursday so I thought we could ask eachother questions to get any help we may need and to aid revision.

Also, if anyone has any useful P1 resources/notes they wouldn't mind sharing here that'd be great!

Here's some questions from the spec:
1. How to reduce the energy transfer from a building.
2. What is the role of free electrons in conduction through a metal?
3. Explain evaporation and the cooling effect this causes using the kinetic theory.
4. Define: payback time.
5. Compare the use of different types of waves for communication (sound/light/microwaves/radiowaves/infrared)
6. Evaluate the possible risks involving the use of mobile phones

I'll post more later. :smile:

what's the answer to 5 and 6? :smile:

I'm not sure, that's why I'm asking haha. :smile:

any ideas of what the six mark question might be on?

5. Different wavelengths have different properties. Long wavelength (radio) detracts round the earth, whilst short(er) wavelength (microwave) reflects of ionosphere. Infra red used in optical fibres and TV remotes.

6. Microwaves heat water and can destroy cells (think microwave). Mobile phones use microwaves, oh no my heads been fried! Most scientists call BS, but not 100% sure. If this come up it will be a source based question.
Oh cr*p I forgot about this exam! I need to start revising :/

There is literally an indefinite list. Just flick through a CGP book and learn it. They could be anything from is nuclear power better than coal, how does red shift support the BBT to describe hoe to insulate a house. Just got to learn the stuff.
Who has the Jan 2014 P1 paper?

what are the main thing i need to know about red shift?

Use the Specification :smile:
If you go onto and hit CTRL+F and then type shift
You can scan the specification for red shift and it will tell what you need to know. Hope it helps :P

yeah boi i'm scanning this till 3am

That it is caused by galaxies travelling away from Earth. The bigger the red shift, the more the waves are spread out and the further away the galaxy- it is also moving faster than galaxies that have been less red shifted. Learn the Doppler effect (same sort of thing) as they will probably relate red shift to that. :smile:

Correct me if I'm wrong, but i don't think red shift actually is caused by galaxies, its just an effect.

THANK YOU!!!! To attach it, you need to make a new post, and click on the icon that looks like a paperclip and a piece of paper in the first row of icons. Once you click it, a window will pop up and all you need to do is press "choose file", find the mark scheme on your computer, and press OK :smile:
