well, i'd guess those terms are pretty equivalent, given that carbon doesn't seem to have a liquid form that we know of. it can be a gas in combination with other gasseous elements, but not by itself... pure carbon only does 'free' (like soot), 'graphite', or 'diamond' - as far as we know, of course.
acording to the periodic table at
http://chemlab.pc.maricopa.edu/periodic/C.html
carbon has a melting point of 4100 Kelvins. I am not aware of any element without a melting point, although we dont have enough heat and pressure to melt carbon anywhere near the surface of the earth, i would not doubt the molten core would hit 4100K. much less jupiter. granted, its much harder to melt than say, PLUTONIUM (ironically, cubic zirconiums are harder to melt), and I dont mean to be an ***, but I am having a hard time with this theory.
