Answer to Question 1
During algor mortis, the body undergoes a process in which it will continually attempt to equalize with the environmental temperature. At average ambient temperatures of 70-72 F the body loses heat at a rate of approximately of 1.0 to 1.5F per hour until the body reaches the ambient or room temperature.
Livor mortis occurs when the human heart stops pumping and blood begins to settle in the parts of the body closest to the ground. The skin appears bluish-purple in color in these areas. The onset of this condition begins immediately and continues for up to sixteen hours after death under average conditions, at which point all lividity is fixed.
During rigor mortis, a chemical change occurs in the muscles, causing them to become rigid. This rigidity subsides as time goes on and disappears at about 36 hours under average conditions.
