What is the relationship between a star's temperature and its radiation output?.
- A.Higher temperature results in lower radiation output.
- B.Higher temperature results in higher radiation output.
- C.Temperature has no effect on radiation output.
- D.Radiation output is independent of temperature.
Model answer
What a good answer should say
- Higher temperature results in higher radiation output.
Explanation
Why this works
As a star's temperature increases, it emits more radiation due to the Stefan-Boltzmann law, which states that the power radiated per unit area of a black body is proportional to the fourth power of its absolute temperature.
