Newton's law of cooling can be used to estimate time of death. (Actually the estimate may be quite rough because cooling does not begin until metabolic processes have ceased.) Suppose a corpse is discovered at noon in a 70°F room and at that time the body temperature is 96.1°F. If at 1:00 p.m. the body temperature is 94.6°F, use Newton's law of cooling to estimate the time of death.
