Final answer:
Determining the age of a body based on temperature is complex and typically handled by forensic experts. The normal body temperature is around 98.6°F, with variations potentially indicating health conditions or, postmortem, the time elapsed since death. Specific details are needed to make an accurate estimation.
Step-by-step explanation:
The query 'How many hours old is a body that has a temp. of 77 degrees?' appears to be related to estimating the time of death based on body temperature. This is a subject matter closely associated with forensic pathology, which is a branch of medicine rather than an exact science like mathematics or physics. The information provided from various sources indicates that the normal human body temperature is approximately 98.6°F, and significant deviations from this norm can suggest certain medical conditions or, in a postmortem scenario, could help estimate the time elapsed since death. It's crucial to acknowledge, however, that accurately estimating the time of death based on body temperature can be complex and is affected by many variables such as environmental conditions, clothing, and the size of the body. Therefore, without specific context, formulae, or situational details, it is not possible to determine how many hours old a body is solely based on a reported body temperature of 77°F.
