question 3
how does the sun manage to maintain an environment in its core that is conducive
to nuclear fusion?

Explanation:

The Sun maintains core fusion conditions via hydrostatic equilibrium (gravity balancing outward pressure from fusion) and high temperature/density. Its massive gravity compresses the core to ~150 g/cm³ density and ~15 million K, enabling hydrogen nuclei to overcome electrostatic repulsion and fuse into helium.

Answer:

The Sun maintains a core environment conducive to nuclear fusion through hydrostatic equilibrium (balancing gravitational compression and fusion-generated outward pressure) and extreme core conditions: high density (~150 grams per cubic centimeter) and temperature (~15 million Kelvin), which allow hydrogen nuclei to overcome electrostatic repulsion and undergo fusion.
