@pouncebaratheon4178 8 лет назад

2:15 There actually is a way to bond helium, though it's a bit gimmicky. What you do is knock out an electron to ionize it, then replace the electron with a muon. Muons are almost exactly like electrons except their mass is about 200 times larger. This greater mass means the muon "orbits" much closer to the nucleus than the other electron (or rather, the wavefunction is much less spread out), so much so that the outer electron shell effectively only has one electron in it. Thus, from the outside, it effectively behaves like hydrogen in terms of its chemical properties (it bonds very easily), despite still being helium in the sense that it has two protons. This is called muonic helium or helium 4.1 (since a muon is about 0.1 amu). Its lifetime is a bit short, though.

@matthewwinchell5608 8 лет назад

Just to clarify, things with very high melting points are actually very often fragile. tungsten carbide and diamond for example are extremely hard, but they will shatter very easily when struck by a hammer. The correct correlation is hardness to melting point. In fact, most very hard things are also very brittle (unable to stretch).

@EpicMouz 8 лет назад

+Giovanni Foulmouth yes in order to make ice you need the water molecules in a specific order due to the shape and polarity of H2O

@binky2819 8 лет назад

+boy638 It's possible. You can increase the pressure on any liquid to turn it into a solid without changing the temperature. You can also reduce the pressure on any liquid to turn it into a gas, again without changing the temperature. But of course, you can't do that to water at home. You need *A LOT* of pressure, which would mean needing access to big laboratories with really fancy equipment.

@q1mera1 8 лет назад

+boy638 yes you can, just search water phase diagram in google and you'll see the pressures required, for example at 350kelvin (around 77ºC) water will solidify at around 1 GPa that is around 10000 the standart atmospheric pressure. Oh and btw water behing incompressible is something we say for low pressures, water is more compressible than say concrete or sand we just call it incompressible to make it easy on ourselfs when comparing it to vapor

Out of curiosity: Why is the relationship between the melting point and boiling point not constant. (Since the compounds with the highest melting point and highest boiling point are different). I'd think that the attraction between molecules would remain constant, but I'm obviously wrong. Why?

@CobaltYoshi27 8 лет назад

Would adding tantalum instead of hafnium to the carbon and nitrogen raise the melting point even more? Because Tantalum Hafnium Carbide is a solution of tantalum carbide and hafnium carbide, and tantalum carbide's melting temperature is 55K higher than hafnium carbide.

@superdau 8 лет назад

+CobaltYoshi27 Unfortunately it's not that simple. For example: water boils at 100°C, ethanol at 78.5°C. But a mixture of both (at least when the alcohol content is at least around 50% by mass) has a lower boiling point than both of them.

@CobaltYoshi27 8 лет назад

superdau That's different though. It's not mixing two substances to create a higher melting point. It's substituting one element from another.

@abeta201 8 лет назад

@CandyflossCottonCandy 8 лет назад

Earth's distance from the Sun varies between about 147 and 152 million kilometers. Given the speed of light as 299,792,458 m/sec and the Sun's radius of 696,000 km, this makes the time taken for the journey (from the Sun's surface to the Earth's) between 8.14 and 8.42 minutes.

hey so just a thought, Wont the pressure on the surface of the sun be less than earth ? so its easier to achieve compounds that can tolerate the surface of the sun ?

How do you even process a material like that tungsten compound if it is so hard and you need such incredible heat to melt? How do you make anything useful out of something that seems almost impossible to modify?

“There’s not a metal that has a high enough melting point to make your jet engine real” Yeah right!

I have a question. If tungsten carbide has the highest boiling point, how did we boil it? Wouldn't everything we put it in to heat just melt before it, or am i missing the point and we computer simulated the answer?

My mind is slow. The green brothers play tricks on me.

Very interesting , but i had to keep checking the conversion from kelvin to Centigrade. IT would be awesome if you could always include '(C)' next to kelvin.
