Which of the following stars would you expect to have the highest density?

• High mass, high volume star

• Low mass, high volume star

• High mass, low volume star

• Low mass, low volume star

In a very very very very long time, our Sun will run out of fuel and transition into a Red Giant. How will its mass change?

(Before ejecting a planetary nebula)

• The giant star will have more mass than our sun

• The giant star will have less mass than our sun

• The giant star will have the same mass as our sun

• This is the wrong answer.

What are the two forces that control the size of a star?

• Gravity pushes inwards, external pressure pushes outwards

• Internal pressure pushes outwards, external pressure pushes inwards

• Gravity pushes outwards, internal pressure pushes inwards

• Internal pressure pushes outwards, gravity pulls inwards

Which of the following stars would you expect to be the hottest?

• Protostar

• Main sequence star

• Outer shell of red giant

• Inner core of red giant

Which of the following stars would you expect to be the coolest?

• Main sequence star

• Outer layers of red giant

• Inner core of red giant

• White dwarf

• Whichever star is wearing sunglasses

Which of the following objects is the most similar to a white dwarf star?

• A nebula

• A main sequence star

• The core of a red giant

• a protostar

Which stars will have the longest main sequence?

• Low mass stars, because of their relatively cool temperatures

• Medium mass stars, because they burn at medium temperatures

• High mass stars, because of their high temperatures

• Extremely high mass stars, the hottest stars in the universe

Which stars will have the shortest main sequence?

• Low mass stars, because of their relatively cool temperatures

• Medium mass stars, because they burn at medium temperatures

• High mass stars, because of their high temperatures

• Extremely high mass stars, the hottest stars in the universe

Why do stars with High / extreme mass not form a Planetary Nebula after their Giant phase?

• The outer layers drift away too fast to form a nebula

• The outer layers do not have the correct mix of elements to become a nebula

• The outer layers are recaptured by the star's intense gravity and cannot drift away

• The inner layers replace the outer layers near the shell of the star
