Which of the following statements describes the relationship between mass and the expected lifetime of a star? larger stars undergo fusion reactions for longer periods than small stars. medium-sized stars undergo fusion reactions for longer periods than larger or smaller stars. smaller stars undergo fusion reactions for longer periods than large stars. a star's mass has no effect on how long it will undergo fusion reactions.

The longest lived stars are small stars, therefore they undergo fusion longer than any others. The mass of large stars causes more reactions which eventually create iron in its core. Once created, the iron causes a chain reaction leading to a super nova. medium stars also burn fuel faster and eventually cannot contain itself and begins to expand until it's fuel runs out. Then it shrinks to a diamond the size of a few city blocks but is more.massive than earth. small stars can live for trillions of years though

The smaller stars undergo fusion reactions for longer periods than large stars.

What is the relation between mass and the life of a star?

The smaller stars undergo fusion reactions for longer periods than large stars. The lifetime of stars depends upon their mass larger the mass smaller will be its lifetime and vice versa.

Smaller stars have a lesser amount of hydrogen present in the core as compared to the larger star. So the hydrogen present in the core will spin due to gravity in the smaller star with less speed as compared to the larger star.

The stability of the star depends upon the rate of reaction occurring in its core. Since smaller stars have lesser hydrogen so the fusion reaction in the core will be slower or happened for a longer period as compared to the larger star.

Hence the smaller stars undergo fusion reactions for longer periods than large stars as compared to larger stars.
