Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Larger stars (stars with more mass) burn hotter and “live” shorter than smaller stars.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion. A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for about 10 billion years .

Detailed explanation-2: -Massive stars also use up the hydrogen fuel in their core faster, despite starting out with much more of it, meaning they live much shorter lives than dwarf stars.

Detailed explanation-3: -Stars can range in sizes from a small star like our sun to stars tens of times the Sun’s mass. Larger stars burn through their fuel faster than smaller stars and die sooner, though they create more new elements in their lifetime.

Detailed explanation-4: -In high mass stars, fusion happens more rapidly than in low mass stars, so they produce more heat and are hotter than low mass stars. Star colors are a function of temperature, with blue for a hot star and red for a cool star.

Detailed explanation-5: -A star’s life cycle is determined by its mass. The larger its mass, the shorter its life cycle. A star’s mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born.

Detailed explanation-6: -Larger stars have more fuel, but they have to burn (fuse) it faster in order to maintain equilibrium. Because thermonuclear fusion occurs at a faster rate in massive stars, large stars use all of their fuel in a shorter length of time. This means that bigger is not better with respect to how long a star will live.

Detailed explanation-7: -The more massive a star, the more it must burn hydrogen fuel to prevent gravitational collapse. Because they burn more fuel, more massive stars have higher temperatures. Massive stars also run out of hydrogen sooner than smaller stars do.
