<p>oh yeah, i just remembered a question. it was like if voltage decreases, temp _____. it was increases, i believe.</p>
<p>I definitely agree that the voltage question was difficult. </p>
<p>I thought there was one where we required outside knowledge (moon)…</p>
<p>“oh yeah, i just remembered a question. it was like if voltage decreases, temp _____. it was increases, i believe.”</p>
<p>i dont remember that, did it just require u to look at some data/graph?</p>
<p>i got a lot of Bs for the whole test</p>
<p>yea temp increases</p>
<p>what was the answer to the moon one? i believe i chose A but not completely sure.</p>
<p>I believe I said everything goes down (because less g = gravitational pull), because of less mass than earth</p>
<p>Kinetic energy would be less. KE = 1/2 MV^2</p>
<p>@kevinnewhouse I said because the gravity on the moon is less… isn’t that correct?</p>
<p>does anyone remember the question with answer that said something like 20-40 was at least 75% and the others were more varied?</p>
<p>@bvfor4
Yea i said that it was becuase the gravity on the moon is less…</p>
<p>Whats the average Science curve?
Also, like everyone is saying, the voltage ones threw most people off.
and @KevinNewhouse yes your right.</p>
<p>***!!! That science section was INCREDIBLY HARD/IMPOSSIBLE. I feel like I didnt take the same test as you people… Btw as a rule of thumb, mass is constant. Weight is influenced by gravity, but mass is the same regardless of the gravity. I hate when people on these boards determine if something is right or wrong without even looking it up.</p>
<p>yeah i put the gravitational pull on the moon is less</p>
<p>What was the answer to the range of temperatures in the voltage question? I guessed 88K but had no idea how to do it</p>
<p>^^ Lucky you! The answer was 88K. You could reach this answer by first determining from the graph that R > 0 at about 6mV. Going back to the table you find that 6mV is equivalent to 88K. You then need to realize that R = 0 for all temperatures less than 88K. Thus, your range is 0K-88K, which is 88K.</p>
<p>Does anyone remember how to do the percent water question or even what it was? My friend told me it was 12% but I just need something to trigger my memory to know if I got that right cuz I coulda sworn I put 50% for some answer…or was that a seperate question? It was on the passage with the reactants losing mass or whatever and was represented on a graph.</p>
<p>^^^ Its mass started at around 100g and then it lost H20 and its mass went down to ~88g thus 12% was lost</p>
<p>However, there was a question that asked what the mass would be for the last reactant if the original was reduced to 50g instead of 100g. the answer to that I believe was 20g</p>
<p>Also, was one of the answers like that reactant with boiling point of 123 C or something it was asking which would solidify first i think</p>
