Me in July Tidal interactions between the giant planet and the other Jovian moons. The inner most moon IO is the most thermally active.
Io's heat is generated by tidal forces produced by the gravity of Jupiter and the other three Galilean moons.
Mars is smaller than Jupiter. Mars is solid, but Jupiter is mainly gases and liquid hydrogen with perhaps a solid core. Jupiter has an internal heat source and a strong magnetic field. Mars has 2 tiny moons. Jupiter has 4 large moons plus about another 60 moons. They are some of the main differences.
Io is the innermost of the four large moons (Galilean moons) of Jupiter. Its closeness to Jupiter means that its surface is in a constant state of flex, the gravity from Jupiter distorts its surface, generating heat and flaws in the surface of the moon. This means that volcanoes are a common occurrence on Io.
Yes. If it were life like we know it here on earth, it would have to be located deep in Europa's ocean near thermal (heat) vents in the ocean's floor.
Me in July
Europa gets the amount of sunlight that moons of Jupiter can expect to get; not much. Jupiter is about 8 times further from the Sun than the Earth is, so it gets about 1/64th as much solar energy. "Enough"? Enough for what?
The innermost of Jupiter's large moons, Io, is constantly kneaded by gravity from Jupiter and the other three large moons. Friction from this process creates an enormous amount of heat, which in turn causes intense volcanic activity. Io has the most volcanic activity of any object in the solar system. Europa, the next moon out, is subject to similar forces but to a lesser degree. Heat from gravitational effects helps to create an ocean of liquid water beneath Europa's icy surface. The liquid water has created features on the surface reminiscent of Earth's tectonic plates.

The moons heat does pass through the mantle but it hardly makes heat. its is mostly cold day and night.
It becomes a solid and gives off heat.
