> "First, we need to know how the mass of Hell is changing in time. So,
> we need to know the rate that souls are moving into Hell and the rate
> they are leaving. I think that we can safely assume that once a soul

state

> Since there are more than one of these religions and since people do
> not belong to more than one religion, we can project that all people

> can expect the number of souls in Hell to increase exponentially. 
Now,

> Law states that in order for the temperature and pressure in Hell to
> stay the same, the volume of Hell has to expand as souls are added.

> This student got the only A.
