properties of stars (temperature, mass, and luminosity). word bank: temperature, mass, dwarfs, decrease, luminosity, giants 0. as the mass of a star increases, so does its ______ 10. as the mass of a star increases the expected lifespan will ____ 11. the color of a star is an indicator of its ____ 12. small stars are called ____ 13. larger stars are called ____ 15. why do larger mass stars live shorter lives? 16. what color stars are the hottest? ____ 17. what color stars are the coolest? ____ life cycle of stars. word bank: decrease, gas, high mass, red giant, nebula, main sequence, white dwarfs 18. all stars start as a ____ star. 19. after fusing hydrogen to helium, a star will expand into a ____ 20. the mass of a star will continually ____ over its lifetime. 21. only ____ stars will supernova. 22. stars similar to our sun (and smaller) will not supernova and will become ____ 23. all stars form from a cloud of ____ inside a ______

Explanation:

• 9. A more massive star has greater internal pressure and temperature, leading to higher luminosity.
• 10. More massive stars burn through their fuel faster, so lifespan decreases.
• 11. Color is related to surface - temperature, with hotter stars being bluer and cooler ones redder.
• 12. Small stars are called dwarfs.
• 13. Larger stars are called giants.
• 15. Larger mass stars have more fuel but burn it at a much faster rate due to higher core temperatures and pressures.
• 16. Blue stars are the hottest.
• 17. Red stars are the coolest.
• 18. All stars start as a nebula, a cloud of gas and dust.
• 19. After fusing hydrogen to helium, a star will expand into a red giant.
• 20. As a star burns fuel, its mass decreases over time.
• 21. Only high - mass stars will supernova.
• 22. Stars like the Sun and smaller will become white dwarfs.
• 23. All stars form from a cloud of gas inside a nebula.
