Question

Which star burns energy at the fastest rate?
A) The sun
B) A star with twice the mass of the sun
C) A star with half the mass of the sun

Answer 1

Explanation:

As the hydrogen-burning shell becomes denser, it becomes hotter and burns hydrogen at a faster rate, making the star even brighter and larger. If the core's temperature reaches 100 million K, then the helium in the core will start to burn by nuclear fusion.
