Jupiter is a rocky planet with a thick ocean of liquid hydrogen.


Molten rock

Solid hydrogen too,and it helps give it its great magnetic field.Bert


"At supercold temperatures, hydrogen molecules first condense into a liquid, then a solid with the molecules intact. When squeezed together, the molecules stack up into a solid form. ... Planetary scientists are convinced metallic hydrogen must exist inside Jupiter, to generate that planet's powerful magnetic fields." - Google

the metallic hydrogen remain liquid even if the temperature is very
low. It is the pressure which make it metallic liquid

to produce a magnetic field the hydrogen have to liquid and conductor.
It is the liquid's move which produce the magnetic field

the hydrogen may be gas, liquid, metallic liquid, slush, solid, metallic
solid
