We have all watched the movie “Titanic" where Jack dies to save the love of his life, Rose, by placing her on a door as he stays in the freezing

water dying slowly. Most of the audience were wondering why Jack didn't go on the door too, although there was a plenty of space.Using Buoyancy, explain why Jack didn't have any chance to survive and they would have all sunk. Note that they would survive only if the volume submerged is that of the door.
