Question

which statements are true about energy and matter in stars? select the three correct answers. (2 points)
□ energy in stars causes the fusion of light elements.
□ energy and matter are both conserved in stars.
□ only energy is conserved within stars
□ only matter is conserved within stars.
□ some matter is converted into energy within stars
□ all energy is converted into matter in stars.

Explanation:

In stars, high - temperature and pressure conditions cause the fusion of light elements like hydrogen into helium. According to the mass - energy equivalence principle (E = mc²), some matter is converted into energy during nuclear fusion in stars. Also, the total amount of energy and matter combined is conserved in stars (mass - energy conservation).

Answer:

Energy in stars causes the fusion of light elements.
Energy and matter are both conserved in stars.
Some matter is converted into energy within stars.
