<p>Remember, Pressure x Volume= NR x Temperature</p>
<p>N is the number of moles.</p>
<p>This makes sense, because imagine one person in an elevator. Seems comfortable. Now, imagine 100 people in an elevator. It’s pretty crowded. Pressure works similar to that.</p>
<p>Was the KMT question scientist 3 or 4? I was really running out of time at that point and didn’t have time to reread the scientist’s opinions. Did they even talk about the KMT in the background info? Seems unfair if they didn’t…I didn’t even learn about it until AP chemistry (which I couldn’t take until after a year of regular chemistry)</p>
<p>Scientist 4, as atoms and molecules in gaseous states do collide elastically and do not attract/repel each other (assuming ideal gas theory conditions)</p>
<p>no KMT was not in the background knowledge which is why that was a terrible question and you had to know it ahead of time</p>
<p>^ well, you can kind of determine through analysis. All the scientists said molecules repulsed each other except scientist 4. He was the outlier. That’s what makes him seems like the answer.</p>
<p>yeah i think i guessed scientist 4, but still</p>
<p>Yes it was scientist 4</p>
<p>This question explicitly required outside knowledge, something the creators of the act do not do very often.</p>
<p>You can look up the kinetic theory of gases to find out if you got the question right or wrong.</p>
<p>Well, you do realize that all the theories were basically similar, except 4. That should give it away.</p>
<p>How bad would the curve on this be? Like this science section was kinda harder than the ones I had been taking in the past (at least the pressure/gas laws passages were rough, and some of the rat cola stuff was rough too)</p>
<p>usually sceince tests don’t get curve. For the people looking for 34 and above, the science seemed really easily. The best you can expect is 1 point.</p>
<p>I was able to guess scientist 4, but I thought that question was extremely unfair as it required outside knowledge. I’m willing to bet that the curve accounts for the question pretty high up the converted score scale, i.e., -1=36, -2=35, or -3=34.</p>

<p>Did anyone else find the star passage confusing? What were everyone’s answers?</p>
<p>The science section was brutal. The passage about the stars killed me omg</p>
<p>So. Was the radius 2piR or piR. I put 2piR. Also, just to confirm, the last question on the rat one was Study 1 since the women could have ate anything.</p>
<p>The circumference of a circle is 2piR, but since it was a semicircle you had to divide that by 2, giving you piR.</p>
<p>What was the star passsage?</p>
<p>Did you guys get G and B (or reverse order, same thing) for the last 2 questions on science?</p>
<p>For the question on the tank passage that asked if you put an insulating lid on the top of the container, would the temperature raise a lot (i think it was above 16 degrees), raise a little (between 14 and 16 degrees), decrease a lot or decrease a little, what did everyone put?</p>
<p>I can’t quite remember what I put for that - if the original temperature of the water was 14 degrees, I put the answer that said “something or equal to 14 degrees.” What did you put for the one that asked about which Stream (A or B) would be less likely to freeze at the top?</p>
<p>@ohheythere
The temperature would raise a little ( between 14 and 16 degrees). the temperature without the lid as 14 degrees, that sets the lower boundary. The temperature at the beginning of the experiment was 16 degrees, this sets the upper boundary.</p>
