you need to admit, if hell continuously required to feel in ppl , at some point it has to expand to keep all the ppl and assuming if hell wanna keep ppl at high temperature all the time while expanding - hell have to absorb the heat from somewhere thus my closest assumption will be endothermic.

As I said earlier, it's a trick question. One designed to see if the student actually know the meaning of the term.

But whether hell is real or not, does not mean it cannot be used to teach science. There are physics teachers who use Superman and other superheroes in their classes to teach their subject. The point is to get the students attention. Not convince them that superheroes are real.
