Question

select the correct answer. which property of a star can help us deduce its surface temperature? a. color b. distance c. stellar parallax d. mass

Explanation:

The color of a star is related to its surface temperature. According to Wien's law, hotter stars emit more energy at shorter wavelengths (bluer colors), and cooler stars emit more at longer wavelengths (redder colors). Distance (B) is about how far a star is from us, not its temperature. Stellar parallax (C) is a method to measure distance. Mass (D) is related to other stellar properties like luminosity and lifespan in some cases but not directly to surface temperature like color is.

Answer:

A. color
