What will happen if liquid 02 were to be pressurized even more? Would it turn into a solid?

Answer 1

O2 is Oxygen, not water. Most solids have a positive heat of fusion and are more dense that when melted (water ice is an exception). If that's the case with O2 then, yes, it will solidify if the liquid is pressurized sufficiently.

Answer 2

I tyhink the above answer is talking about H20 i.e. water.

"Oxygen as an element certainly can be made into a solid.....
Liquid O2 and solid O2 have a light blue color and both display unusual paramagnetic properties, due to the negative exchange energy between neighbouring 02, . Liquid O2 is usually obtained by the fractional distillation of liquid air."

In case you're wondering:
Liquid and solid O3 (ozone) have a deeper color of blue
