<p>We were lacking a science thread so here it is...
General consensus is that this section was harder than in the past.
Post thoughts/curve predictions/questions here.
I'll try to keep this post updated with questions and answers so it will be easy for people to come and look.</p>
<p>I thought the science was pretty hard. I had to guess on 4 of the arguing scientists because I ran out of time.</p>
<p>I think I got all the arguing scientists right. We’re going over kinetic molecular theory right now in my chem class so that helped. </p>
<p>The section I struggled on was the one with the fluids. I did awful I think.</p>
<p>My natural curiosity in the various sciences really helped me on the science test. I believe people get caught up in the unfamiliar terms and their heads begins to spin as they can’t make reason of any of these words. </p>
<p>I’m sure the curve will be beneficial in this case.</p>
<p>If pressure increases the size of the Balloon increases too right?</p>
<p>Idkhur: Yeah, scientist B thought pressure would decrease so he was the only appro[riate choice.</p>
<p>Efeens it sounds as if you may be looking at a 36 based on what you’ve said. Congratulations man. :)</p>
<p>Scientist 3 was the most correct, right?</p>
<p>I agree with pk12ab. I put scientist B as well.</p>
<p>Oh thank god…i had to guess like 5 but i thought it was ok</p>
<p>Jdan: For which question?</p>
<p>Thanks pk12ab. However, the more I think about the science the less likely I think I got a 34. The science curves are usually absolutely brutal for high scorers. I took a previously administered practice test where my -6 was a 27. Other has good curves but I’m not banking on it. Best case scenario I got minus 2 or 3 and pull off a 33/34. Science will make or break my 36.</p>
<p>Which scientist is most accurate according to Kinetic Molecular Theory? The last question on the arguing scientists</p>
<p>The most correct scientist was scientist 4. Particles do collide with each other.</p>
<p>Which scientist thought molecules would not move with constant temp And pressure? That was tje exact question i think</p>
<p>efeens, I believe in you! Aha, its gonna be close but if you pulled off a 36/36/36 a 34 will be okay. </p>
<p>Idkhur: Scientists one and two</p>
<p>Likeasir: yeah but he said they don’t attract each other (which they do) and they don’t lost energy (which they do)</p>
<p>Science for me was pretty difficult</p>
<p>In the one about cola intake in women…the was a question that dealt with which group of women in Study 1 had the highest amount of women in it…either I totally couldn’t find it or my guess of It could not be found was right. I never took a science test before where “It cannot be found” was the right answer.
I put that as my answer because the graph represented bone density and intake of cola.
Any thoughts?</p>
<p>@Tenmore: I put that too! That question stumped me because I kept thinking it couldn’t be that easy.</p>
<p>Tenmore: I was surprised too! I read the question and not the choices initially, so I looked and looked and said to myself, “This isn’t even possible!” I then looked at the answer choices.
“Oh.”</p>
<p>Here is the kinetic theory of gases for everyone</p>
<p>Kinetic theory makes many assumptions in order to explain the reasons gases act the way they do. According to kinetic theory:</p>
<p>Gases consist of particles in constant, random motion. They continue in a straight line until they collide with something—usually each other or the walls of their container. </p>
<p>Particles are point masses with no volume. The particles are so small compared to the space between them, that we do not consider their size in ideal gases.</p>
<p>No molecular forces are at work. This means that there is no attraction or repulsion between the particles.</p>
<p>Gas pressure is due to the molecules colliding with the walls of the container. All of these collisions are perfectly elastic, meaning that there is no change in energy of either the particles or the wall upon collision. No energy is lost or gained from collisions.</p>
<p>The time it takes to collide is negligible compared with the time between collisions.</p>
<p>The kinetic energy of a gas is a measure of its Kelvin temperature. Individual gas molecules have different speeds, but the temperature and kinetic energy of the gas refer to the average of these speeds.</p>
<p>The average kinetic energy of a gas particle is directly proportional to the temperature. An increase in temperature increases the speed in which the gas molecules move.</p>
<p>All gases at a given temperature have the same average kinetic energy.</p>
<p>Lighter gas molecules move faster than heavier molecules.</p>
