Mainly its temperature.

Mass decides a stars ultimate fate.
No, there would have to be an atmosphere and water as well.
The main factor that shapes the life and death of a star is its mass. The more massive the star, the faster it burns through its fuel and the faster it evolves. The mass of a star determines its temperature, luminosity, and eventual fate, such as whether it will end as a white dwarf, neutron star, or black hole.
I assume you mean, "how long a star lives". That depends mainly on the star's mass, with more massive stars using up their fuel way faster than less massive ones.
The two main factors that determine the characteristics of a star are its mass and its age. The mass of a star determines its temperature, size, luminosity, and lifespan. A star's age affects its stage in its life cycle, such as whether it is a young, main-sequence star or an older red giant.
The key factor that determines the soundness of an argument is the truth of its premises.
Most stars are primarily made of hydrogen and helium. The composition of a star affects its characteristics and lifespan because the fusion of these elements in the star's core produces energy through nuclear reactions. The balance between the outward pressure from nuclear fusion and the inward force of gravity determines the star's size, temperature, brightness, and how long it will live.
