The life of a Star (pages 468-471).
1. Explain gravity.
2. Explain how a nebula turns into a cloud leading to a star(3 steps)?
3. What happens when a star runs out of the fuels needed to produce energy?
4. What is a supernova? During this stage, what happens to the core of the star?
 When our Sun eventually swells into a red giant star, its outer layers will grow to be
about 100 times its present size swallowing up Mercury, Venus, Earth and maybe
even Mars
5. What is a neutron star?
6. What is a pulsar?
7. What type of stars can eventually turn into a black hole?
8. What is a black hole?
 The word hole is misleading because it sounds as though there is nothing there; it
actually has a huge amount of matter packed into a sphere only a few kilometers
across. It is so compact that a handful of it would have a mass of 10 billion cars.
9. Describe the life of a low mass star and that of a star 10 times bigger than our sun
10. Explain the terms red giants, red supergiants and white dwarfs.
11. Explain how a star goes from Major part of life to death.
Become familiar with figure 2 on page 469.
