@seyll00 Yeah, it was in the comprehension. It was pretty tough.
@bobthebuilder13 Hmmm… I didn’t think that one was right but I wasn’t sure, and still am not.
I guess there’s no point in fretting over the answers now, what’s done is done. If I can lock in a 750+ on this or 700+ on Lit I’ll be done with standardized testing until my final AP season in May 
@bobthebuilder13 that was the answer for why heat moves from hot to cold im pretty sure (2nd law of thermo)
the answer also said something about entropy. It had nothing to do with volume
You’re confusing two of the choices. The answer for heat goes from hot to cold was “The entropy of the universe always increases” or something.
The reason that I chose that answer was that P * (change in V) = work. So i think it makes sense
You’re doing work on the system, increasing its kinetic energy, and therefore the temperature as well.
I thought the internal energy and work were related by q(heat)=u(internal energy)+w(work)… does that make sense? Could it be used to answer the question? I’m a bit confused right now.
Yeah I think so. It would get at the same answer right?
use two other equations to plug into there.
Plugging those two into your equation, I think the answer makes sense.
@bobthebuilder13 I thought W=P(Delta)V could only be used under the assumption of ideal gases.
Not sure. But all the other answer choices didn’t seem to make sense.
@bobtheboy The expanation you put forth makes sense. Seems like I got that wrong (forgot about W = PV). I put the one about specific heat, and though that could be a part of it as you mentioned (your first step involves q=mc(delta T), I think the answer you chose makes more sense.
Any advice for those taking it in November?
What about the questions#11,12 kinetic and potential energy of pendullum? What about the potential energy and speed one when satellite is closer to earth in elliptical pathway and when it is far away. Also I think the answer to the aeroplane one was that all PE not PE and KE
@Muhammad For the Pendulum i wrote Kinetic Energy as b-a Or a-b (Dont really remember) and for Potential energy just b or a. I drew a Kinetic Energy curve over that Potential Energy one just to check. Wbu?
I put potential was a, and kinetic was b.
Kinetic Energy was b and Potential Energy was a? Where was the need to subtract? B marked the region from above the point on the PE curve, while A marked the region from that point down to the x axis of the graph?
@bobthebuilder13 Exactly, yeah?
But if u draw a KE curve wont it give u the subtracted thing as the answer?
i said potential was a
