|And not all liquids are solvents. |
So just because those compounds are less dense as a solid than as a liquid doesn't mean they are also solvents.
Oh, Joe. Yes they are. Every liquid is capable of dissolving some other things. That’s all that’s required to be a solvent.
Density of solid vs. liquid isn’t the cause solvent properties. At best it’s caused by the same root property.
However, per your earlier question, 100% of solids that are less dense than their liquids float in their own liquid. Relative density is what makes things float.
Wrong! Not all liquids are solvents.
And no, plutonium is only 2.5% more dense as a liquid meaning a big solid chunk of it would not float in liquid plutonium.
Ahh. Joke never ceases to entertain. First it was that frequency = wavelength, now a solid that is less dense that its liquid form will sink.
The difference in density of water at 4C and at 20C is approximately 0.2%. Yet this is sufficient to make the temperature at the bottom of the oceans 4C.
The bottom of the ocean is not ice.
Try it and see. Take a big chunk of solid plutonium and place it in a vat of liquid plutonium and watch it sink
Because ice is less dense than water. Physics 101. But if solid plutonium is less dense than its liquid form, as you claim, why would it sink? You don’t make any sense.
Now think this through, Joe. What amount of displacement is required for an object to float?
With icebergs just the tip generally shows. There is about a 10% difference between salt water and ice with respect to density.
So by overthinking the issue I get the chunk of solid plutonium suspended in liquid plutonium but not floating on top.
But seeing there is about a 2.5% difference between fresh and salt water I will be able to test that next time I make it to the beach.
You are aware we know how to calculate this? I get this isn't something you’ve studied, but why do you assume no one else has? Joe, this is high school physics, but it’s a good thing that you’re interested in it, so here’s a place to start.
Your link discusses submerged objects. Submerged means it is underwater. The buoyancy keeps it from sinking to the bottom.
That is what I described.
Only to the clueless.
There is a difference between floating on and being suspended in.
It isn't my fault that you are unable to follow along
Could you name some examples of things that float on a substance vs. those that are submerged in it?
