Some main sequence stars will eventually form black holes. Table 3 gives the mass of four stars. Which star in Table 3 is most likely to form a black hole?

Table 3: Star | Mass in kg --- | --- Arcturus | 2.2 x 10³⁰ Betelgeuse | 2.2 x 10³¹ Cygni A | 1.4 x 10³⁰ The Sun | 2.0 x 10³⁰

A star's final fate depends on its initial mass. - Low-mass stars (like the Sun) end up as white dwarfs. - High-mass stars end up as neutron stars. - Only the most massive stars have sufficient gravitational force to overcome all other forces and collapse into a black hole after a supernova explosion. To find which star is most likely to form a black hole, we must identify the most massive star in the table. - Arcturus: 2.2 x 10³⁰ kg - Betelgeuse: 2.2 x 10³¹ kg = 22 x 10³⁰ kg - Cygni A: 1.4 x 10³⁰ kg - The Sun: 2.0 x 10³⁰ kg Comparing the masses, Betelgeuse has the largest mass (due to the higher power of 10), so it is the most likely to form a black hole.
