<p>Do you know the more specific parts of that question? I dont really remember that one…was it at the beginning of the test? I think I remember getting ionization energy for the first question or something like that.</p>
<p>was the answer choice for 2 x 32 E?</p>
<p>@mscasdfj:
You asked earlier about the light/radiation questions.
I said ultraviolet radiation (ozone blocks that), infrared radiation (Earth’s surface emits that), and gamma rays (radioactive substances often emit those).</p>
<p>for the set of 5 questions where they had like
increase in boiling point, decrease in freezing point, molar mass, mass, and density…which ones did you guys put? does anyone remember the questions for those?</p>
<p>@mscasdfj</p>
<p>For one of those it was like “which one increases as you add more stuff” for which I chose mass.</p>
<p>I got 2 TTCEs, there are about 10+ between the two TTCEs</p>
<p>10+ Qs…typo</p>
<p>2 ttce ultra/infra/gamma for those
Teacher says infrared is visible light</p>
<p>Yeah, my 2 TTCE’s were pretty far apart (maybe like 4 questions into the TTCE section and then the 4th to last one or something like that).</p>
<p>For the light section I searched up online info and it should have been UV (sun), infrared (earth), and gamma (common emissions).</p>
<p>You sure it wasn’t visible light instead of infrared ? I answered infrared but found nothing online abou it :P</p>
<p>so I think I skipped four and have one wrong… how much do you think the curve will be on this test ?? Is this harder/easier than usual ?</p>
<p>@arabguy</p>
<p>Yeah, check this image: <a href=“http://earthguide.ucsd.edu/virtualmuseum/images/EarthRadiativeBalance.html[/url]”>http://earthguide.ucsd.edu/virtualmuseum/images/EarthRadiativeBalance.html</a>. It shows that earth emits IR radiation. :P</p>
<p>I skipped one question and I probably have around two wrong? I’m not really sure since I tend to make stupid mistakes haha. I think this test will probably have an average or a slightly better than average curve, but that’s just my gut feeling.</p>
<p>I’m pretty sure I got an 800 with none or one wrong. I thought that test was fairly easy. I remember the majority of the questions so if you guys want me to put together like a answer something, you guys can help me with that.</p>
<p>I’m pretty sure that there were only TWO TTCE’s in the entire section.</p>
<ol>
<li>the temp at which liquid boils can be lessened by lowering the pressure above the liquid because (something about pressure and vapor pressure)</li>
<li>reaction with ideal gases (something about mole ratio and volume ration are the same in the same temp and pressure) because like two ideal gases (same moles) at same temp and pressure occupy equal volumes</li>
</ol>
<p>Other than these two, there were no TTCE</p>

<p>I’m down for the answer document idea, though I don’t remember a lot of the questions. I also got the same TTCE’s as you did–that’s good to know. :)</p>
<p>What was the equation that had highest increase in entropy? I put the one with the largest increase of gas molecules from reactant side to product side, but idk. Also what was the t/f questions about gases condensing- something about absorbing energy and bond breaking.</p>
<p>@will2424</p>
<p>please make an answer document!! i’d appreciate that :)</p>
<p>@bmirish898</p>
<p>Yeah, that’s what I put for the greatest increase in entropy as well. I think it was choice D or E (it went from like 2 mols to 5 mols?).</p>
<p>I don’t remember the specifics for the gas question but I know that the first half of the TTCE question was that when a gas condenses, energy is released. Dunno about the bond-breaking part though.</p>
<p>@will
I dont think that the first one is TTCE. The second part of the question said ‘…vapor pressure, which changes as temperature increases.’ Vapor pressure doesn’t vary with temperature, atmospheric pressure does</p>
<p>Vapor pressure is dependent on temperature the most.</p>
<p>I remember shrodinger was mentioned in a question but I forgot what it was about…I’m pretty sure I didn’t choose him in my answer though.</p>
<p>I think I have 5-6 wrong … any chances of an 800 ?</p>
