It's been a very long time since I had a physics course that might address
this.

Suppose I have a 10x10x10' room that has one human in it. The room is
fully insulated. A human produces 100 watts, but 1/2 of that is in heat.
What I would like to know is if the room was initially at 60F, what
temperature would it be at say 6 hours later? I would think this somehow
involves knowing the specific heat of a human body and air. Roughly or
exactly, how does one make the calculation? I have no idea what the
specific heat is for either item.

If the human produces 100W, but only half of that is heat, what's the other
50W ?

Do you need to know the Specific heat of the human? As a species we regulate
our temperature to be more or less constant, so unless the temperature of
the room increases to a similar temperature, the only thermal mass that will
be warming up will be the air in the room.

I'm sure you can google the density and specific heat capacity of air at
room temperature, and use it to roughly calculate the temperature after 6 x
3600 seconds @ 100 Watts.

Why do you want to use degrees F and the room size in feet ? Celsius and
metres would be easier
