Question

how does a stars classification on the h - r diagram relate to its projected lifespan? a high - mass, hot stars live longer, while low - mass, cool stars live shorter lives. b low - mass, cool stars live longer, while high - mass, hot stars live shorter lives. c cooler stars fuse elements together faster. d all stars have similar lifespans regardless of their classification.

Explanation:

High - mass, hot stars consume their nuclear fuel at a much faster rate than low - mass, cool stars. Low - mass stars have less fuel but burn it slowly, allowing them to live longer. High - mass stars burn through their fuel quickly, resulting in shorter lifespans.

Answer:

B. Low - mass, cool stars live longer, while high - mass, hot stars live shorter lives.
