unique/interesting properties of matter

Water expands both when it cools and warms.

>>9055939
That's really fucking cool

>>9055939
water doesnt expand when it cools, once it reaches a certain temperature it expands relative to before and a solid forms.

>>9055955
So it expands when it freezes? Interesting.

Superconductivity is pretty cool.

Hot water can freeze faster than cold water.

>>9056061
yes, from 4 to 0 degrees Celsius, apparently

>>9054574
diamagnetic metals (like copper, aluminium or gold) though not attracted by magnets, get "stuck"(harder to move) in strong magnetic fields due to inducted currents

>>9056089
What do you mean stuck ? Care to give me a scenario as an example ?

Superfluid Helium has some interesting properties.

It's been a while since I've taken pchem so forvige the shotty explanation. Helium is essentially a perfect ideal gas. There is virtually no interaction between helium atoms with one another so when it's cooled down to a few degrees above absolute it allows quantum mechanical interactions rather than macro or atomic interaction to be shown.
