We all have had the experience that a room full of people always feels warmer than when the room is empty. Ten people are in a 4.0 m x 6.0 m x 3.0 m room at 20oC. If each person gives off heat at a rate of about 100 W and there is no heat loss to the outside of the room, what is the temperature of the room after 10 min? At 20oC, the density of air is 1.2 kg/m3 and its specific heat at constant pressure e is 1005 J / (kg ∙ oC).
