Scientists have discovered a new star, and after analyzing it, they find it to be a spectral class F star (yellow-white). What would scientists predict would be the surface temperature of the star?
5,200 – 6,000 K
7,500 K – 10,000 K
6,000 – 7,500 K
10,000 K – 30,000 K
What would scientists predict would be the surface temperature of the star?

The correct answer is 6,000 – 7,500 K.
Explanation: Spectral class F stars have surface temperatures ranging from approximately 6,000 to 7,500 Kelvin. These stars appear yellow-white and are characterized by their hydrogen and ionized metal absorption lines in their spectra.
