Question

Which statements are true of the reactions in the Sun?Check all that applyA. They occur between hydrogen atoms.B. They occur only between helium atoms.c. High speed collisions cause the reactionsD. They are fission reactions

Answer 1

The sun is a dense collection of gas having high temperatures and high pressure.

This high temperature and pressure force the atoms of hydrogen to move faster and collide with each other.

This results in the nuclear fusion of hydrogen atoms into helium.

Thus, options A and C are correct.
