Problem
A submarine of volume V=6m3, with solid carbon fiber walls of negligible
thickness and internal temperature t=20∘\mathupC was submerged to the
depth d=3km. Suddenly, the walls ceased to hold and the submarine shrank.
What is the temperature inside?
Assume that the submarine did not break, but only shrank (although we know from
experience that this is not a realistic assumption), and that the passengers
and the cargo put up only negligible resistance to the shrinking (this is
a realistic assumption).
