Question

The average human body gives off heat at a rate of about 100W. A law office
with 6 clerks measures 6m wide, 6m long, and 3m high. Assume that only 1/3 of
the radiated body heat in this office goes into warming the air and that the air was
a chilly 15ºC when work began at 8AM. Assume further that the office remains at
normal atmospheric pressure the entire day and that no heating systems are turned
on before 10AM. Find the final air temperature at 10 AM.
