Question

select the correct answer from the list. (1 point) as a stars size increases, its luminosity increases. as a stars temperature decreases, its luminosity increases.

Explanation:

Luminosity of a star is related to its size and temperature. Larger - sized stars generally have higher luminosities as they have more surface area to radiate energy. Higher - temperature stars also have higher luminosities as the energy radiated per unit area increases with temperature. So, as a star's size increases, its luminosity increases, and as a star's temperature increases, its luminosity increases.

Answer:

As a star's size increases, its luminosity increases. As a star's temperature increases, its luminosity increases.
