Consequently, its surface is hotter, and most of its molecules have been torn apart by the heat. One interesting feature of the atmosphere of Jupiter is its turbulence. Because Jupiter is rotating so rapidly, the gas around the material moves at extremely high speed. The cloud-tops of Jupiter are rather cold, since the planet is far from the Sun. On the other hand, the mass of Jupiter is large, so the inside of the planet is under great pressure.
High pressure means high temperature, so down deep the in atmosphere, Jupiter is very hot.
Just like on earth, when warm air hits cold air, you get storms. Now let's contrast Titan with the planet Mercury. Both are roughly the same mass, but while Titan has an atmosphere, Mercury doesn't. The answer lies in the planet's temperature. Mercury is close to the Sun, and is extremely hot.
