A room with approximately 100 people measures 15m x 20m x 10 m and the indoor temperature is 20 o C. Let's assume that each person in the room gives an average of 350 kJ of heat per hour. Find the room temperature at the end of 30 minutes, assuming that the walls of the living room do not take heat and pass and that the air conditioner does not work for 30 minutes.
