Question

The stability of a star is a balancing act between its own internal forces of gravity and the heat energy it produces via fusion reactions. Explain this statement

Answer 1

gravity tries to pull all the mass in the star toward the center.
However the heat energy makes every chunk of mass move faster and faster trying to expand the particles outward like steam escaping from a kettle.

Answer 2

Ohh, ok, makes sense, thanks. :)
