state 4: plasma

[Fantasixsixsix]

@allAboutDEADSPACE plasma is found on earth. And can be quite easily made.

Bose Einstein Condensates still can be made by humans, however the process does not quite qualify as "quite easily"

Were is plasma?

Good video even without sound!

brilliant video guys this will be great for teachers as there knowledge for kids is a bit highly separated . you know kids they can learn a lot from things like this!!

This video is a favorite on Malawi

@GrezH Lol your confusing me now, in another post you said we would not be able to breath if lighter gass move up because oxygen would all go up, now your saying its heavier then "quote" water? I have totally lost the plot haha So are you saying Oxygen is a light gas or a heavy gas? I may of miss read or miss understood what your trying to say? 

[GrezH]

@MrNativeDancer Interestingly, a water molecule is one atom of oxygen (mass 16u) joined to 2 atoms of hydrogen (mass 1u each) so has an overall mass of 18u. However, a pure oxygen molecule containing 2 oxygen atoms has a mass of 32u. This means that oxygen molecules are heavier than water molecules. It's the forces between them that cause the change from solid to liquid to gas, and also their density.

@GrezH Exactly if trees stop making oxygen we all die lol your right! Wind blows oxygen,and mixes it with other dense particles slowing and even preventing it from rising, for example water is Oxygen mixed with Hydrogen, both gasses rise but when mixed become heavy thus sinking back to earth as water. Thats heavy you know you try carrying a bucket full. But when gasses seperate and become pure and light weight they move only upwards until contaminated so to speak hard to explain here though.

[GrezH]

@MrNativeDancer Sorry, but if "light" gases move "only" up, and "heavy" gases move "only" down, we should not be able to breathe in oxygen while standing on earth. It would have moved up and left layers of "heavier" gases (such as carbon dioxide) just above the surface.

[GrezH]

@MrNativeDancer If a gas "can escape its container," it is not being contained, so it's not really in a container! Due to differing densities, gases will show layering when mixed together, but pure carbon dioxide will not sink to the bottom of a container, it will completely fill it. All liquids are condensed gases, but they show different physical properties, which is why they're called liquids.
