<p>What was the answer to why did they stir the bowl or whatever material it was in? I put it was to sink all the dense material. I don’t think it was to distribute heat because heat naturally flows from hot to cold and so it would naturally distribute itself</p>
<p>I got the same thing as u alsnayyan09</p>
<p>I agree it would sink. To the person wondering why ice then floats, as the temperature of water in its liquid state decreases, the density increases, normally. However once ice hits a threshold somewhere around -2 to 2 degrees Celsius, its density is far lower than water, then as it continues to get colder the density increases once more. As the water is heated and the liquid expands and turns into gas form (90 Celsius they stated) the ice begins to go back toward the original lowest density point, decreasing its density lower than the water until it completely melts. That is why ice floats on hot water and can’t really work for this problem. Ice typically will have a lower density than liquid water in most situations.</p>
<p>What did scientist 1 and 4 agree on and what were some answers to the 4 hypothesis questions?</p>
<p>^</p>
<p>1) Something was absorbed by proteins.
2) Cant remember</p>
<p>There was a question that asked why the four deicers were set at 4 degrees Celsius. The two options I remember were because it was the freezing point of all four and because it was the average winter temperature. I went with the winter temperature, can anyone confirm this?</p>
<p>^ went with that too.</p>
<p>I went with the winter option and did anyone get 150 for the solid nacl percent in 1000g or something</p>
<p>^ was that the last question, of the six</p>
<p>It was 150.</p>
<p>The winter one was the last question of the first science section (out of 7) and the 150 g one was the third to last question on the first science section.</p>
<p>Super hard! Especially the first passage. You couldn’t just skip the passage reading for that one.</p>
