A closed auditorium of volume 25700 m3 is filled with 2050 people at the beginning of a show, and the air in the space is at a temperature of 291 K and a pressure of 1.013·10^5 Pa. If there were no ventilation, by how much would the temperature (in K) of the air rise during the 1.5-h show if each person metabolizes at a rate of 83.9 W?
