analysis questions

1. where does a stars energy come from? (passage 1)
2. why is the metaphor vice used in passage 1?
3. how is a stars creation of energy connected to the creation of new elements? (passage 1)
4. stars are very massive. why doesnt a star collapse into itself while it performs fusion? (passage 2)
5. what process keeps stars alive?
6. what 2 things can happen to a star when this process ends?

Explanation:

1. A star's energy comes from nuclear fusion in its core, where hydrogen atoms combine to form helium, releasing energy in the process.
2. Without the full context of Passage 1, it's hard to say exactly. But a metaphor like "vice" might be used to emphasize a constricting or powerful - like a vice - force or situation related to the star.
3. During nuclear fusion in a star, as hydrogen fuses into helium and heavier elements are formed in more massive stars, energy is released. The creation of new elements is a by - product of the energy - generating fusion process.
4. The outward pressure from the energy released during fusion balances the inward gravitational force trying to make the star collapse.
5. Nuclear fusion keeps stars "alive" as it provides the energy to counteract gravitational collapse.
6. When the fusion process ends, a star can either become a white dwarf (if it's a low - to medium - mass star), a neutron star, or a black hole (if it's a high - mass star).

Answer:

1. Nuclear fusion in the core.
2. Cannot be determined without full passage context.
3. New elements are formed as a by - product of the energy - generating fusion process.
4. Outward fusion pressure balances inward gravitational force.
5. Nuclear fusion.
6. Become a white dwarf, neutron star, or black hole.
