The oxygen is blue and paramagnetic (i.e. attracted to a magnet) for the same reason: the two unpaired electrons in its outermost orbital. The electrons both create a magnetic assymetry in the oxygen molecules and absorb light in the red portion of the visible spectrum.
Liquid oxygen has a pale blue color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. ... Because of its cryogenic nature, liquid oxygen can cause the materials it touches to become extremely brittle.

Turning into liquid can be called fusion or melting, depending on what form (gas/solid) is turning into liquid. Liquid Oxygen is blue in colour because its molecules absorb and red wavelengths and cannot absorb the blue ones, so it looks blue. The conditions for Oxygen turning into its liquid form are -182.96 C or -297.33 F.
