    Physics, Chemistry and Biology: Post your doubts here!

    Could someone please explain the process of drying gas to me? I read that when collecting a gas using downward delivery, the gas is dried through concentrated sulphuric acid. How and why?

    Oh, alright. Thanks. :D And if it's not too much trouble, could you explain question 9 from the same paper? The one about the train.

    AS Physics P1 MCQs Preparation Thread.

    Thanks. I understood up until the part where you find the period, but beyond that, I don't see how you got 0.01, and thus 10mscm^-1. Could you please elaborate on the last point? Sorry for being a bother. :P

    You're going to need an institute to help you with bio, chem, and phys practicals, but apart from that, sure.

    How is a temporary/induced dipole involved in (CH3)2CHCH3 (2 methylpropane)?

    Chem P2 any guesses ?????

    My guess is that there will be a question on enthalpy, Kc, and some Inorganic, as these were largely missing in the MCQ section. I'm talking about paper 22, btw.
