Concept explainers

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

Police arrive at the scene of a murder at 12AM. They immediately take and record the body's temperature, which is 90°F, and thoroughly inspect the area. By the time they finish the inspection, it is 1:30 AM. They again take the temperature of the body, which has dropped to 87°F, and have sent it to the morgue. The temperature at the crime scene has remained steady at 82°F. At what time did the crime happen? Assume normal body temperature be 98.6°F.
