3. blue

4. White dwarf stars are much hotter than Red Supergiants 15. List the color of the stars from hottest to coldest: Blue, White, Yellow, Orange, Red 16.

5. red giants

Explanation:

Main sequence stars have a Morgan-Keenan luminosity class labeled V. red giant and supergiant stars (luminosity classes I through III) occupy the region above the main sequence. They have low surface temperatures and high luminosities which, according to the Stefan-Boltzmann law, means they also have large radii. White dwarf stars are much hotter than Red Supergiants 15. List the color of the stars from hottest to coldest: Blue, White, Yellow, Orange, Red 16. The hottest stars are the blue stars. A star appears blue once its surface temperature gets above 10,000 Kelvin, or so, a star will appear blue to our eyes. The lowest temperature stars are red while the hottest stars are blue. Astronomers are able to measure the temperatures of the surfaces of stars by comparing their spectra to the spectrum of a black body. Most stars, including the sun, are "main sequence stars," fueled by nuclear fusion converting hydrogen into helium. ...

As stars begin to die, they become giants and supergiants (above the main sequence).

1. Sketch a picture of the components of a galaxy. Write the name of our galaxy as the title of your drawing.2. Investigation3. Ervin is a current 5th grade student. One weekend he went on a trip to the beach with his family. After arriving at the beach, his mother put sunscreen on him to protect him from the Sun. Ervin and his older brother decided to go swimming in the ocean. While swimming his brother pointed out how large the Sun appeared. Later in the day, the Sun was covered up by dark clouds. When the Sun got covered, Ervin decided to stop swimming.At school on Monday, Ervin’s class was learning about the Sun. Ms. Chabert, his teacher, posed 3 questions to the class. Ervin was excited because he was able to use what he learned about the Sun at the beach to answer each question correctly. Use what YOU know about the Sun to answer the questions that Ervin’s teacher posed to the class. Answer in complete sentences please.A. Is the Sun a star?B.
