What is the LDS conception of Hell?
“Latter-day scriptures describe at least three senses of hell: (1) that condition of misery which may attend a person in mortality due to disobedience to divine law; (2) the miserable, but temporary, state of disobedient spirits in the spirit world awaiting the resurrection; (3) the permanent habitation of the sons of perdition, who suffer the second spiritual death and remain in hell even after the resurrection.
