1) Describe the process of a plasma core forming at the center of a forming star. Be sure to explain the role that temperature plays in this process.
2) Why does our sun remain the same size (what forces are in balance)? How will this change when the hydrogen fusion moves away from the core?
3) Explain why a giant star has a lower surface temperature even though it is giving off more energy. What does this say about the change in size of the star as a whole (does it get slightly bigger or considerably bigger)?
4) Why does a white dwarf form during the planetary nebula process? What causes the white dwarf to cease collapsing? What is the absolute final product from the evolution of a low mass star?
