3.Newton’s Law of cooling states that the rate of change of the temperature of an objectis proportional to the difference in the temperature of the surroundings into which it is placedand that of the object itself.A body is discovered in a room with constant temperature of 30C.From the time of death the body will radiate heat into the room according to Newton’s law.Onarriving at 9.40pm the forensic scientist measured the body temperature as 36.1 and afterfurther investigation at 11.00pm again measured the body temperature which was found to be34.2.Assuming that the body had a normal body temperature of 37.5 at the time of death,atwhat time did the person die?
