<p>@lizzie1773 was that the “to ensure uniform composition” or something… because if so i said that too. or was that a diff option?</p>
<p>No I think that was a different option. The choice I picked was “For even temperature distribution” or something along those lines.</p>
<p>@CHS, I thought pressure, volume, and temperature were only related when it came to gases.</p>
<p>Primarily these are interrelated in gas laws. Though, in general, an increase in temperature will induce and increase in volume due to thermal expansion.</p>
<p>i know that both water and object wre heated and it said the oblects wontchange in size or something.</p>
<p>can someone say what they got for sink/float? i put float and the only explanation that remotely made sense lol, i dont remember why though. i also got .16, decrease only for the chart with the mercury/gasoline, stirring for even distribution, and some others discussed. i got the 800 and >15 ones wrong though :/</p>
<p>THIS TEST WAS IMPOSSIBLEEEEEEEE</p>
<p>I think we already discussed that one. Try to look at the previous posts before posting questions please. The general consensus was that it sank</p>
<p>I said that it would sank because the water would become more dense than the object after heating. Was that correct?</p>
<p>No, water would not become more dense. If you heat water, it becomes less dense. </p>
<p>It was it would sink because water would become less dense</p>
<p>lol watch a -4 be like a 23 on this section</p>
<p>@imadropout the only reason i put float was because i was thinking of oil in water. if you boil water, the oil stays on top (floats). that was my only reasoning</p>
<p>@diddly </p>
<p>I’ve never heard of that but sure, I guess. However, they were talking about objects I’m pertty sure and I think that a liquid on top of a liquid vs an object on top of a liquid may behave differently. Maybe not. </p>
<p>Look at this [Temperature</a> and Density | Chapter 3: Density | Middle School Chemistry](<a href=“Temperature and Density | Chapter 3: Density | Middle School Chemistry”>Temperature and Density | Chapter 3: Density | Middle School Chemistry) for more information.</p>
<p>@imadropout, according to my online dictionary, the exact definition of an object is “something that can be seen and touched.” it didn’t specify what state it was in. idk, i thought it was vague anyway ugh</p>
<p>What… is that even relevant…?</p>
<p>I’m pretty sure the question asked if an object was placed in water and then the water increased in temperature, would the object sink or float…</p>
<p>Why else would it have answers of sink or float… lol…
You don’t say oh the orange juice sunk into the water or the oil floated on water. Sinking and floating itself implies objects.</p>
<p>i don’t understand why the object would sink… i get everyone’s reasoning, but then why do ice cubes float in hot water? ice cubes, like the object, are cooler than the water… for this reason I said it would float.</p>
<p>exactly my reasoning too!^^ in addition to the oil, i was thinking of ice. just because water gets less dense as it gets hotter doesn’t meet it will get less dense than the object originally floating in it. there would have to be a REALLY big change in density</p>
<p>@imadropout, i was just expanding on the term ‘object’ because you implied in your previous post that the material was a solid. sorry if i didnt explain, im falling asleep right now lolol</p>
<p>@relativelysmart</p>
<p>It’s more of a “common knowledge” assumption type of question. When water is heated, the molecules that comprise it move further apart as they need more room to move. As a result, the volume of the water increases and the density decreases, because now the same amount of water takes up a larger area. So, therefore, the object would most likely sink, because the density of the object will be greater than the density of the water.</p>
<p>Figure 2 showed the amount of the object above the water at a specific time. As time increased in water, the object became more and more immersed in the water. If you had taken this graph into account as well as the water’s decreasing density, the answer would be indisputably that it sunk.</p>
<p>but then why does ice float in hot water if we established that a colder object would be more dense and therefore sunken? i am convinced that the answer to the question was sink, but i am genuinely curious about why this doesn’t apply to ice…</p>
<p>Apparently hot water is still more dense than ice. In the case of the passage, none of the object would be above the water (in accordance with Figure 2) and therefore we can also assume that the density of the object would have been more than the hot water</p>
<p>I didn’t get to read the question the thoroughly. I assumed that the object would also expand according to the volumetric heat expansion coefficient of the material. But now that I think about it, the water will probably expand more than the material.</p>
