    That sucks. I totally hate those sorts of questions too. In my head I know exactly what's expected, but... why is it all so 'wordy'?! It's always where I lose marks.

    A-level Physics is so diluted! Rant rant, haha

    I've Only just started revising for this as I've been cramming for G485, which didn't go too badly! (Touch wood!)
    Reading through the book, I've come to realise how nice this module is compared to G485!
    Last exam.... I need to nail this!

    Does anyone have a list of all the possible experiment that could perhaps come up in this paper? It would be of great help!

    Those questions are pretty straight forward where you will be given all the values. And its just a matter of substituting the values and finding out whatever they're asking which most of the time is volume or pressure or something like that. Just be careful of using the Avogadro's Constant where necessary.

    If u do chemistry u should be fine with the whole moles concept and using avogadros constant. Really the tough bit is just remembering the expressions correctly as n=moles and N=number of particles/molecules for the two separate equations. Oh...and temperature in Kelvin ofcourse

    Question about Kepler's third law. So it's defined as "the square of a planet's orbital period is directly proportional from its cubed radius from the sun". However can we use the equation for other things, such as the moon orbiting the Earth?

    as a definition only talk about planets round the sun. but satellites & moons follow the same relationship
