question 1 (1 point)
which of the following correctly lists the color of stars from coolest to hottest?
a blue, white, yellow, red - orange, red
b red, red - orange, yellow, white, blue
c blue, white, yellow, red, red - orange
d red, red - orange, yellow, blue, white

Explanation:

To determine the correct order of star colors from coolest to hottest, we use the knowledge of stellar temperature and color correlation. Cooler stars emit light in the redder part of the spectrum, and as temperature increases, the color shifts to red - orange, then yellow, white, and finally blue (the hottest stars are blue).

• Option a: This order is from hottest to coolest (blue is hottest, red is coolest), so it's incorrect.
• Option b: Red (coolest) → red - orange → yellow → white → blue (hottest) follows the correct temperature - color relationship.
• Option c: The order here is incorrect as it misplaces red and red - orange and has an incorrect progression from blue to red.
• Option d: The order of blue and white is incorrect; white stars are hotter than yellow but cooler than blue, and this option misarranges them.

Answer:

b. Red, red - orange, yellow, white, blue
