How do astronomers think Jupiter generates its internal heat?

A) radioactive decay

B) internal friction due to its high rotation rate

C) chemical processes

D) nuclear fusion in the core

E) by contracting, changing gravitational potential energy into thermal energy

Astronomers think Jupiter generates its internal heat by contracting, changing gravitational potential energy into thermal energy.

Answer: Option E

Explanation:

The internal heat of Jupiter is primarily the primary heat released during gravitational collapse when its creation occurs. Because of their large dimensions, this giant plant was heavily heated by creating surrounding material on their cores.

The largest planet, Jupiter was the hottest. Part of this warming may still remain on such large planets. In addition, it is possible that this giant, mainly gaseous planets produce heat after they are formed as a result of slow contraction. With such a large mass, even a small shrinkage can generate high heat.
