(05.03 lc)
which of the following stars is likely to emit the most energy into space?
the brightest star
the dimmest star
the smallest star
the coldest star

Explanation:

The brightness of a star is related to the amount of energy it emits. A brighter star emits more energy. A dimmer star emits less energy. A smaller star (assuming same type) would have less material for fusion (main energy - producing process in stars) and thus emit less energy. A colder star has less thermal energy to radiate out.

Answer:

The brightest star.
