How do the atmospheres of gas giants like Jupiter and Saturn differ from those of terrestrial planets?

I wonder what will happen to a human being set foot on this gas giant planet. Will we burn or freeze?

Answer 1

Well first you can’t “set foot” on a gas giant, your ship just keeps plummeting into the increasingly dense gas until it melts or gets crushed from the pressure.

Eventually the pressure and heat is so great in there that there’s no real distinction between liquid and gas, so the interior is more of a vast ocean of compressed supercritical mush.

There’s probably a solid core at the very center, but it’s understandably hard to measure.
