Higher mass stars "burn" faster due to the increased pressure in the core.
Stars are basically big leaky buckets of light, and a higher mass main-sequence star has a similar energy density of light within it, and it takes that light a similar time to leak out (often hundreds of thousands of years), but it has a much larger volume filled with that light, making it a bigger and leakier bucket, hence more luminous.
No. you could time them.
They burn the same gases as any other star. The gases are just weaker. After the supernova only the core of the star is left, so it is just the core of the star.
The most massive stars; they will use up their fuel much faster than less-massive stars. or even low mass star which is less then half the mass of our sun may able to last more then a trillion years that is longer then the universe age
Higher mass stars "burn" faster due to the increased pressure in the core.
Heavier stars will usually burn faster than lighter stars.
Because larger stars burn their hydrogen faster than smaller ones.
unscented candles burn faster because its made with a type of wax that doesnt have fuuels and the less the fuels the faster it burns
Larger stars have a larger mass and stronger gravity, which means their cores are more compressed. The greater compression leads to a higher core temperature, which causes faster fusion.
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.
Main sequence stars do not really exist - well they do, but read on. Main sequence is a stage in a stars life - where it converts hydrogen into energy, not a particular star or type of star. All stars go through a main sequence, from the smallest to the largest.However, in general, the larger the star, the faster it will burn off it's fuel.
Larger stars, or to be more precise, more massive stars, have more gravity; therefore they get denser and hotter, therefore the nuclear reactions occur much faster. This is quite disproportionate; a massive stars may be, say, a hundred times more massive than a red dwarf, but burn fuel at a rate that is millions of times faster.
All stars 'burn' hydrogen
Yes. The more massive the star, the faster if develops - and the faster it grows old and dies. A very massive star will die in a supernova explosion, which may result in a neutron star or a black hole.
The least massive stars, i.e., the red dwarves. More massive stars get more pressure and temperature, and therefore burn their fuel up faster. For comparison, while a red dwarf might shine for trillions of years, the most massive stars run out of fuel after just a few millions of years.
Softwood usually. It depends on the density of the woods you are burning.
