Imagine that the three stars listed below all formed at exactly the same time, but in different locations of the universe. Cosmo Star is an O spectral class star with a MS lifetime of 3 million years. Its life will eventually end as a SN type II and become a black hole. Cosmo Star is located in a galaxy 10 billion light years (ly) from Earth. Ollie Star is a K spectral class star with a MS lifetime of 12 billion years. Its life will eventually end as a slowly cooling white dwarf. Ollie Star is located in the MW at a distance of 10,000 ly from Earth. Sullivan Star is an F spectral class star with a MS lifetime of 5 billion years. Its life will eventually end in a SN type I that will completely destroy Sullivan Star. Sullivan Star is located in a galaxy 6 billion ly from Earth. Which of these stars final end states will first be viewed on Earth

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
