Yes (and its temperature depends on its size),
the bigger (and hotter) the shorter its life.
Yes, the color of a star is determined by its temperature, with hotter stars appearing blue/white and cooler stars appearing red. Generally, larger stars tend to be hotter and appear bluer, while smaller stars are cooler and appear redder.
The colour of a star depends on its temperature. Massive main sequence stars can have surface temperatures of 50,000 K. Smaller stars such as the Sun have surface temperatures of a few thousand K. Red giants have relatively low surface temperatures of about 3,600 K, but are still very bright. 'K' or 'Kelvin' is a temperature measurement, with 0 Kelvin equal to absolute zero equal to -273oC.
The color of a star is determined by its surface temperature. Hotter stars emit more blue light, while cooler stars emit more red light. This relationship is described by Wien's Law, where the peak wavelength of light emitted by a star is inversely proportional to its temperature.
Stars in the constellation of Ursa Major. The stars themselves are made mainly out of Hydrogen.
The color of a star reveals its temperature. Blue stars are hotter than red stars, with temperatures ranging from about 10,000 K to 40,000 K and higher for the most massive stars.
The Color of stars depends upon their surface temperature.
depends on all the stars.
It's mass and temperature.

luminosity and temperature depend on their size but also on their mass
The length of time a star burns depends on its temperature and mass. It's certainly not possible to calculate this to the level of precision of seconds, and it's difficult to do so to the level of precision of millennia.
It really depends on the star. But most stars consist mainly of hydrogen-1.
It depends on what you want to measure: their numbers, distance, mass, temperature, ...
The differences in spectrum are mainly due to: * Differences in temperature between the stars * Differences in chemical composition * Differences in relative movement (redshift / blueshift, due to the Doppler effect)
It all depends on the temperature of the individual star. [See related question]
