Why do stars with smaller masses burn longer than stars with larger masses?

Stars with larger masses have stronger gravity; this results in more pressure; which in turn makes the star hotter. As a result of the higher temperature, they will shine brighter, and burn their fuel much faster.

What is larger than the ocean?
That Is a difficult question because what are you asking about? Most planets in our solar system are larger than all oceans combined as well as most stars. I think all the continents combined is smaller that the oceans combined.
What unit do astronomers use to measure the masses of stars and star like objects in the universe?
The official unit for mass in science (and elsewhere), of course, is the kilogram. In astronomy, for ease of comparison, the masses of stars, and even galaxies, are often expressed in "solar masses", meaning multiples of the mass of our Sun.
Are the corpses of stars that are small or medium to begin with?
The "corpses" of stars may be white dwarves, neutron stars, or black holes (and perhaps "quark stars", but this is still very speculative). In general, the least massive stars - which also tend to be smaller - will become white dwarves. These are much smaller than "active" stars, but much larger than neutron stars or black holes. The more massive the star, the SMALLER will the white dwarf be - due to the increased gravity. Our Sun has a diameter of 1.4 million kilometers; other stars can be several times smaller, or larger - but a white dwarf only has a diameter of a few thousand kilometers. More massive stars become neutron stars, which have a diameter of 20-30 km - and an immense density, similar to that of an atomic nucleus. The most massive stars end up as black holes. Here, the only "diameter" that can be observed from the outside is that of its event horizon, which is directly proportional to the black hole's mass. A black hole the mass of the Sun would have a Schwarzschild radius (the radius of its event horizon) of about 3 km; therefore its "diameter" would be about 6 km. A black hole a billion times the mass of the Sun would have a Schwarzschild radius of 3 billion kilometers.
Why dwarf stars are so bright?
Dwarf stars are NOT "so much Bright", the smaller the star is (provided it is on the main sequence) the less intrinsically bright it is.
Why is it necessary to use different types of telescopes in astronomy?
Larger telescopes are often used to focus on one specific star or distant formations. Smaller telescopes view broader areas of stars or larger formations.
Are Some stars as small as earth?
Yes, there are even stars smaller than earth. Most are collapsed ancient stars that have become neutron stars and have masses slightly larger than our sun currently has.
Are some stars about as small as earth?
Yes, there are even stars smaller than earth. Most are collapsed ancient stars that have become neutron stars and have masses slightly larger than our sun currently has.
Why do some stars survive longer than others?
Because larger stars burn their hydrogen faster than smaller ones.
Do hot stars or cool stars tend to live longer?
The smaller a star the longer it lives. Smaller stars can live up to 200billion years, while a supergiant only lives about 10 billion years. Cooler stars live longer because they don't burn as much energy as a hotter star, while the larger the star, the shorter its lifespan
Which star lives longer smaller or bigger?
Smaller stars last longer.
How does the size of our Sun compare to the size of other stars?
Most stars are smaller than the Sun, but those that are larger can be a lot larger.
What size stars have longer lives?
larger stars have longer lives, because as stars burn they are slowly burning up fuel and begin to cave in on themselves. the larger, the more fuel, the more fuel, the longer lasting.
How does the size of the sun compare to the sizes of the stars?
Most stars are smaller than the Sun, but those that are larger can be a lot larger.
Are stars smaller than planetesimals?
No. Stars are many times larger than planetesimals.
Which star is live longer gaint star or smaller star?
The smaller stars
Are most stars are smaller or larger than the sun?
Most stars are smaller than the sun, falling into the red dwarf category.
Are red stars bigger than blue stars?
Red stars can be smaller or larger than blue stars as there are two types of red star. Red dwarfs are much smaller than blue stars while red giants are much larger than blue stars.
