    Kind of bull**** that that program is only in some select areas :holmes:
    Our college says that its extremely costly to be the hub in the region (we don't pay any money, nor do other colleges and the students they're sending here, but the hub college takes up all of the cost of the programme).

    If it's going on right now I couldn't attend anyway :mmm: Stupid family moving back to Australia

    I am using the HE+ website now though. It seems to have everything (I imagine it would be nice to actually have a class though).

    Ours starts in January.

    The topics on the HE+ website differ from the topics covered in the actual programme though. For example, the topics on the website for Maths are Proof-orientated, whereas the topics we're covering are Curves, Group Theory, Fractals, Multivariate Calculus etc.

    Can someone help me with this chemistry question please?

    Both C3H8 and C4H10 can be liquefied and used as fuels for camping stoves. Suggest, with a reason, which of these two fuels is liquefied more easily.

    I though it would be C8H8 since it would have a lower boiling point and so would liquefy easier as the bonds can be broken easier than C4H10.
    However the mark scheme says that the answer is C4H0, since it has a high boiling point/ stronger IMF.

    Bit confused as to why that would allow it to liquefy more easily.

    C4H10 has one more carbon than C3H8, therefore more surface area for London force to act on (intermolecular force), therefore higher boiling point, which means that it is easier to become liquified,

    This is from Jan 2013 AQA unit 1 right? I remember this question because I sat the exam.
    If this is the case, can you post a picture of the question, I'm sure it came with some data

    But wouldn't there be more energy required to overcome these IMF forces than necessary for C3H8?

    Notice the data they gave you is for boiling points (so to get from liquid to gas). Using the table, it would be easier to liquidify C4H10 as opposed to C3H8 because its easier to achieve -1°C as opposed to -42°C

    Applied for Engineering (Economics and Physics as back up choices)
    How do we apply for these things, is it too late? And are they the Oxford equivalent of the Cambridge subject masterclasses or something else?

    I'm doing IB - I don't think I'll be getting mocks at all before or after Christmas!
    But I'm going to by crying doing Maths everyday over Christmas; it's damn tough and I need to do it

    Well I have gone from art college to general college, back to art college and now going back somewhere else for 6 months and start again in September. Been a crazy time but at least I have a sense of where I am going now.

    yup, more energy required to overcome the imf force in C4H10, so easier to be liquified
