Question

using the h-r diagram, which type of star is likely to have the greatest mass?

1. red giants
2. white dwarf
3. main sequence star
4. blue supergiant

Explanation:

On the H - R (Hertzsprung - Russell) Diagram, mass is related to a star's position. Blue supergiants are high - mass stars. Red giants are evolved stars with lower mass than blue supergiants. White dwarfs are remnants with very low mass. Main sequence stars have a range of masses, but blue supergiants are among the most massive stars. So, Blue supergiant is likely to have the greatest mass.

Answer:

1. Blue supergiant
