Corrected entry: At the end, when Jack Hall finds his son in the library, he opens a door to the room where all of them were staying. The door is completely frozen. Opening the door by it's handle should have caused the handle to break, if not shatter, at that temperature. It would not have just opened as easily as it did.

Correction: Its only frost all over the walls and door handle. The freezing point of a metal door handle is much lower than the temperature depicted in the movie. The door handle would have to be immersed in liquid nitrogen in order to fracture and break apart like you say it should.
