From what I learnt, if it goes from the right hand side to the left on the PV diagram, work is done on the gas because the gas is compressed. If the gas expands, work is done by the gas meaning it goes form the left to the right.
Didn't B-C go right to left tho and so shiuld be included? What do you think full ums and A* boundary will be?
Me too...with that P-V diagram question, wasn't the straight bit on the top to the left of the curve I calculated as well, decreasing in volume? Meaning work had to be done on the gas? Just trying to understand my flaw...

What is the BC gas compression thing you're on about? It wasn't in thermal and nuc section, was it? I don't remember it lol. Hope I didn't miss out a whole page or s/t hahaha

How confident are for A* in further maths? I think i'll be close, maybe 5 ums away
Pretty, still got S2 and FP3 on monday, but sat M3, M2 and FP2 so far and they went good I think... Yeah? Hopefully you'll fall on the right side of the boundary! :-)
I don't know lol, I don't remember most of them was just kind of hoping for an unofficial MS. Although I have checked a few with another user on here.
The only one i think I kind of messed up is the first distance question. I used pythagoras with a triangle of base 1 AU and height 2.7 AU or whatever it was and calculated the hypotenuse and converted it into meters. But i think since it asked for maximum distance you could've just added 1 AU to 2.7 AU.
