Liquid Salt Superconductor

AI Thread Summary

Adding salt to liquid nitrogen will not create a superconductor, as only specific materials can achieve superconductivity at liquid nitrogen temperatures, and salt is not one of them. Superconductors exhibit a unique property of repelling magnetic fields rather than being attracted to them. Therefore, placing a magnet above the nitrogen and salt mixture would not cause the nitrogen and salt to rise with the magnet. The discussion clarifies the limitations of superconductivity and the behavior of superconductors in magnetic fields. Overall, salt does not contribute to superconductivity in liquid nitrogen.

I was wondering also if you put a magnet above it, then lifted the magnet up,would the nitrogen and salt come up too?

Unfortunately not. Only a few special materials become superconducting at LN2 temperatures and salt isn't one of them.
In addition superconductors aren't attracted to magnets - they tend to repel magnetic fields.

Thread 'Is space stretching or is new space being created?'

Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky? Thanks - rev

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
