Answer 2

The temperature of stars and their energy output

Stars emit energy through a process called nuclear fusion, where hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the process. The temperature of a star's surface is directly related to its energy output. Hotter stars have higher surface temperatures and therefore emit more energy compared to cooler stars.

Answer: The hotter star emits more energy

In the given scenario, we have two stars with different surface temperatures: one with a surface temperature of 6000 °C and the other with a surface temperature of 15000 °C. Based on the information provided, the star with the higher surface temperature of 15000 °C would emit more energy compared to the star with the lower surface temperature of 6000 °C.

The relationship between temperature and energy output is described by the Stefan-Boltzmann law, which states that the total energy radiated by a star is proportional to the fourth power of its surface temperature. This means that a small increase in temperature leads to a significant increase in energy output.

Therefore, the star with the higher surface temperature of 15000 °C would emit more energy than the star with the lower surface temperature of 6000 °C.
