Across
  1. 2. layer of the Sun where energy and heat are transferred by thermal convection through thermal columns
  2. 4. relationship type for pressure and volume
  3. 7. the distance between successive crests
  4. 8. how many hydrogen atoms are required to fuse in order to form one helium atom?
  5. 10. the classification for high-mass and medium-mass stars on the H-R diagram
  6. 13. the bright yellow visible surface of the Sun
  7. 14. a cloud of gas and dust that all stars start off their life as
  8. 16. a particle representing a quantum of light, or other electromagnetic radiation, that carries energy proportional to its frequency
  9. 17. light waves that are traveling vibrations of both electric and magnetic fields
  10. 18. shows the spectrum of EM wavelengths emitted by a substance, with bright lines due to the emission of specific wavelengths
  11. 20. the average kinetic energy of all the atoms or molecules of that substance
  12. 21. the amount of space the particles have to move in or are contained to
Down
  1. 1. the amount of pushes the particles do on their container
  2. 3. layer of the Sun where energy and heat are transferred by a process called thermal radiation
  3. 5. the pinkish-red layer above the surface of the Sun that is thick and riddled with jets of hot gases
  4. 6. the wispy outermost layer of the solar atmosphere that extends millions of kilometers into space
  5. 9. method used to produce energy in most stars
  6. 11. shows the spectrum of EM wavelengths passed through a substance, with dark lines due to the absorption of specific wavelengths
  7. 12. the star in the center of our solar system
  8. 15. As our Sun's amount of hydrogen decreases over time, what will increase in our Sun?
  9. 19. this force keeps stars stable over time and keeps them from exploding due to the high temperatures and pressure of fusion in their cores
