What metal has a density of 10.5 per cm3?
There is no metal with that density. The closest would be the beta allotrope of the radioactive metalloid polonium (element 84) : 9.38 g/cm3. Other close matches would be Bismuth - 9.76 g/cm3 Lutetium - 9.84 g/cm3 Thulium - 9.32 g/cm3
How can the composition of an object be determined using density?
If you had an object whose composition was entirely unknown, you could not analyse its composition by density alone. There are an endless number of possible combinations of materials that would have any given density. However, in some circumstances density does allow you to determine composition. If for example, you have an alloy of copper and zinc, but you do not know the relative proportion of the two metals and you would like to find out, you could determine that proportion by measuring the density, since copper and zinc each have a different density, and the problem can be solved as a simple algebraic equation.
What are the boiling point of metals and non- metals?
That would depend on what substance your talking about. Different metals and such would very in temp drastically!
What property of these metals would allow such a separation?
What property of these metals would allow such a separation?
Is expanded polystyrene a thermosetting or thermoforming plastic?
Polystyrene is a very poor conductor of heat. This is why its used as an insulator in some products.
Is low density a metal or nonmetal?
Generally, metals have a high density relative to other elements, but there are a few which dont correspont to this rule. But if it was a simple yes or no question, it would be HIGHH!!!! The density of metals is very variable: from lithium (0,534 g/cm3) to osmium (22,61 g/cm3) - from low density to high density.
What does the term density and refractive index mean?
The optical density of a medium is not the same as its physical density. The physical density of a material refers to the mass/volume ratio. Optical density determines how much a light wave is slowed down as it passes through a medium. The more optically dense a material is, the slower that a wave will move through the material.The refractive index is a measurement of optical density. A medium with a low optical density, would have also a low refractive index.For example air, having a low optical density has a refractive index of 1.0003, whereas water, with a higher optical density, has a higher refractive index of 1.333.
Why did you say the sound depend ion the medium through which the sound travel?
Since sound waves need some medium to propagate or multiply through it follows that the nature or density of the medium would directly or indirectly affect the nature of the wave.
Would 1.4 sink or float?
Assuming that the medium in which it is floating/sinking in is water, It would sink since its density is higher than that of water (1.0gcm^-3)
What is radar made out of?
Various metals, plastics, foam, and paint. It is the materials found in the typical electronics one would see in a common electronics store.
How fast would the speed of sound be if you could hear sound in space?
Well, we know that in any material medium, the speed of sound increases along with the density of the medium. The more dense the medium, the higher the speed of sound, and the less dense the medium, the lower the speed of sound. All of this points in the direction that as the density of the medium tends toward zero, the speed of sound in it also tends toward zero. So I guess in space, where the density of material stuff is next to zero, we would expect that the speed of sound would also be next to zero. But consider this: We know that you can't hear sound in space. Since you have already made up a pretend condition for your question, saying that you can hear sound in space, why don't you go ahead and make up a speed too; whatever pleases you.
How do you separate aluminium from iron without a magnet?
One way would be to find a liquid that is chemically inert to both metals and has a density between that of iron and that of aluminium. In such a liquid, the aluminium would float and the iron would sink.

Is medium necessary for flow of current?
Current requires a medium to flow through, gas, liquid or solids. In metals, free electrons allow passing of current from one region to another. In non-metals, they would have to be molten for the molecules to pass the current around since the molecules in a solid can only vibrate. In gases, the molecules are free to move about, allowing current to be conducted (I suppose).
How far will a projectile travel if launched at a speed of 400 feet per second and an angle of 30 degrees?
It would depend on the gravitational field and the density of the medium through which it travels.
How many milliliter is 250g honey?
A typical density for honey is Honey is 1.36 grams/ mL. 250 g honey would therefor be 250/1.36 or 183 ml
