<p>procedure 1 involved putting them in boiling water…so after you take them out of boiling water, they are really hot, to change that hot temperature before letting them cool, you wouldnt put it back in boiling water, you would put it in dry ice</p>
<p>^ you had to know that answer beforehand, it wasnt fair… i just got lucky</p>
<p>thats the only way there is a temperature change before you let them cool to room temp</p>
<p>am i completely misquoting the question, i believe i am correct</p>
<p>it did not ask how do you heat the ball</p>
<p>pretty sure it did, what else is at 100*C</p>
<p>the point isnt to get it 100 degrees.</p>
<p>it said after heating it to 100 degrees, what can you do to change the temperature before letting it cool to room temperature</p>
<p>putting it back in boiling water wont change the temp before letting it cool because it was already at 100 degrees</p>
<p>again unless i am completely misquoting the question…does anybody truly remember what the question exactly said</p>
<p>I could have sworn it said" What did the student do in order to get the spheres up to the starting tempurature?" or something along those lines, and they all were 100*=boiling water…</p>
<p>if the question said that then highteeld, you are right, the student did use boiling water to get the balls in experiment 1 up to 100 degrees</p>
<p>however i am pretty sure it said, after you have done experiment 1 (ie the heating in boiled water), what can be done to the ball to change its temp before letting it cool</p>
<p>if anybody else has any insight on what the wording of the question was, id appreciate it</p>
<p>i didn’t read the whole experiment, but i’m almost positive it never said they used the boiling water in the actual procedure. it just said that the students heated the spheres up before allowing them to cool - the question was asking how they normalized them or whatever before they started cooling them. it wasn’t air and dry ice and molten aluminum i was just kind of like “wth” at, so i’m pretty sure the answer was boiling water.</p>
<p>it has to be boiling water, thats the only thing that is common knowledge</p>
<p>dry ice is common knowledge - its obviously cold, so that wil change the temp of something that is hot from sitting in boiling water</p>
<p>air at room temperature is also common knowledge but not the answer</p>
<p>The question said something along the lines of, “What could have been done to the spheres before hanging at 100* to cool?”… whatever the exact wording may have been, it was clearly asking “what could the balls have been placed in to be heated to 100*?”</p>
<p>yea but when you think about it, does the average high school student know the temp of dry ice? id say boiling water is the pick</p>
<p>statlanta do you remember the question?</p>
<p>the question asked how they raised it to 100, it was hot water. it wouldn’t make sense to heat them, then cool them, and then put them in the air and measure their cooling rates…</p>
<p>Personally, I thought the question asked what they did to cool them after boiling them in hot water. So I put immerse in air at room temperature. Now, I know that answer is shi*t because of what you guys posted. So yeah. Lol</p>
<p>seeking uni i agree with you that if that is what the question said, then boiling water is correct</p>
<p>my issue is that im pretty sure the question said after performing the proceudre in experiment 1 which means after having heated the balls to 100 degrees</p>
