Two stars of the same size have different surface temperatures: 6000 degrees Celsius and 15000

Two stars of the same size have different surface temperatures: 6000 degrees Celsius and 15000 degrees Celsius. Which star emits more energy? a) hotter b) less hot c) stars emit the same amount of energy.

The radiation energy of a star is directly related to its temperature: the higher the temperature of the star, the more its internal energy, and the more energy it emits. In this case, the temperature of the second star is 2.5 times higher. Therefore, the correct answer is: A) hotter.
