24. ••• A room full of people tends to be warmer than when that room is empty. Suppose that ten people are in a 4.0 m × 6.0 m × 3.0 m room initially at 20 °C. If each gives off heat at a rate of 100 W and, assuming no heat exchanges to the furniture, walls, or outside, what would the temperature of the room be after 10 min?

Assume that at 20 °C, the air density is 1.2 kg/m3 and specific heat (at constant atmospheric pressure) is 1.0 × 103 J/(kg·°C).
