3. In movie StarWars XX, "new StarKiller" base is a super big weapon charged by adiabatically absorbing the nearby SUN as demonstrated in Fig. 3. Basically, scientists figure out a way to compress the WHOLE sun into the size of new StarKiller base via an adiabatic process. While keeping the Entropy of sun's ideal monatomic gas constant in the whole charging process, what is the final temperature Tf of the sun gas inside the StarKiller? All parameters you need are: Sun radius R, Sun initial temperature Ti, StarKiller radius r. Both Sun and new StarKiller base are assumed to be uniform spheres, and so the degrees of freedom is three.
