Scientists at the Lawrence Livermore National Laboratory have discovered a new melt curve of hydrogen, resulting in the possible existence of a novel superfluid - a brand new state of matter.

Both ethanol and ether have the same molecular mass, however, their melting points and boiling points are different due to the ethanol containing hydrogen bonding.
