Because a massive star has more pressure on the core, this creates greater temperatures, which increase the amount of nuclear fusion that occurs. This uses more hydrogen and thus the star runs out of fuel much quicker, that a smaller star.
Compared to what ? -- Compared to the surface of Mars, it's 43.7% as much. -- Compared to the surface of Pluto, it's 2.8 times as much. -- Compared to the surface of the Earth, it's 16.5% as much.
It all depends on how big a star is. The more massive a star is the shorter the life span. A blue/white supergiant could last for 10 million years whereas a small red dwarf could last for trillions of years.
It depends on the initial mass of the star - i.e., how much actual material it contains. The more massive a star is, the shorter its 'life'. Most stars average out at roughly the mass of the Sun (certainly within a fairly narrow range either side of it at least) and the lifetime for such stars is therefore about the same as the Sun's - about 10 billion years. Really massive stars like eta Carinae will run through their nuclear reactions at a much faster rate and so will only last for a few million years. Eta Carinae could go supernova any day now!
The stars look small compared to the sun because they are much farther away.
The major difference is that a low-mass star lives much longer. The reason for this is that a high-mass star gets hotter, is much brighter, and uses up its fuel much faster. The difference can be quite dramatic, with some stars being millions of times brighter than others. Also, assuming the star doesn't acquire additional mass, a low-mass star will end up as a white dwarf, while more massive stars will end up as a neutron star, or in the case of the most massive stars, a black hole.
Massive Stars Use Their Hydrogen Much Faster Than Stars Like The Sun Do.

No. They have a much shorter duration.
The Spanish are more formal but life is much less hectic.
Shorter. More massive stars have much higher temperatures and pressures. Although they have a lot more fuel, it is consumed at a much higher rate than lower mass stars. They burn very brightly and hot, but for less time.

Smart phones with monochrome screens typically have a much shorter battery life than Pocket PC devices with color screens.
Devices with monochrome screen have shorter battery life than colour screen devices.
They are briefer but not as engaging. For apex -> (They have as much to offer but are briefer.)
The orbital period depends upon the distance to, and the mass of, the primary. Jupiter, for example, is much more massive than Earth and a correspondingly greater velocity is required to balance out its gravitational pull, meaning that a satellite orbits Jupiter in a much shorter time than it would orbit Earth if it were at the same distance.
