A class of 10 students taking an exam has a power output per student of about 200 W. Assume the initial temperature of the room is 20°C and that its dimensions are 6.0 m by 15.0 m by 3.0 m. What is the temperature of the room at the end of 1.0 h if all the energy remains in the air in the room and none is added by an outside source? The specific heat of air is 837 J/kg · °C, and its density is about 1.3 x 10–3 g/cm3.

Question
A class of 10 students taking an exam has a
power output per student of about 200 W.
Assume the initial temperature of the room
is 20°C and that its dimensions are 6.0 m by
15.0 m by 3.0 m. What is the temperature of
the room at the end of 1.0 h if all the energy
remains in the air in the room and none is
added by an outside source? The specific
heat of air is 837 J/kg · °C, and its density is
about 1.3 × 10-3 g/cm3.
