Answer

Brief Explanations:

  • Nuclear fusion: Stars generate energy via nuclear fusion of hydrogen into helium in their cores. Gravity is a force acting on stars, not an energy - producing mechanism.
  • Composition: Stars are massive gas - based objects. They are mainly made of hydrogen and helium (about 70% hydrogen and 28% helium by mass in young stars). They are not solid (except for some exotic stars like neutron stars which are in a different category and not the typical stars we refer to in basic astronomy) and not composed mainly of liquid water.

Answer:

Stars produce energy through nuclear fusion.
Stars are massive objects composed of gas.
Stars are composed primarily of hydrogen and helium.
